I'm being emotionally abuse on Facebook

Hey guys, just wanted a bit of advice as I’m sure my friends are sick of me constantly asking them for reassurance and to be there for me. I use to be very close friends with this girl who had kids with a complete an utter nasty piece of work, anyway when they were together I was friendly with him as he was with my close friend and that’s only right, even though most people despised of him, I never see the bad in people. Then when they broke up he came to my home a few times to chat and for advice, which I gave him, he then tried it on with me sexually and I obviously declined in which he didn’t like, I then had the decency to tell me friend the mother of his children and it back fired on me for trying to be the good friend by telling her the truth, she then took his side in which I lost all respect for her as I was trying to do right by her for telling her what had happened as o hate things like that on my mind. After this he came to my house and threatened, send me a whole load of abusive threatening voice notes too like the vile human he is because of course he got found out. I drifted away from her because of the situation and clearly trying to do the right thing was the wrong thing, we have briefly spoke since this happened a few times within the last three or so months. This caused me to have severe ocd and have the worst paranoia, I don’t want her in my life, I don’t even have her number saved but today she turned up at my door unexpectedly just to ‘pop in’ although I don’t want anything to do with her, the whole situation makes me feel ill, makes my ocd bad and bad paranoia. What can I do?

i’m going to have a panic attack (i beg that u read) i became very close with this guy i met on omeagle a he definitely told me he was 17 and i told him i was 15 (which i am) and forward a few months he is the guy i go to for mental health support because he has been through the same. and i told him about my first bf when i got him. but then this guy started to get a bit too interested and he asked for nudes. i said no. but then considered what if my bf wants them ?? i want to know that he would like what he saw. so i asked him ( the omeagle guy ) if he would tell me honestly if my bf would like it. it wasn’t a nude it was litterally a bikini top. that’s all. and i’m not gifted so nothing was showing. he told me my bf would love it etc etc. and i was happy. but the omeagle guy got more interested and because i felt like i liked it i kept using it as proof that i’m not gay. and me thinking he was 17 i kind of let it happen as banter while continuously reminding him that we are just friends and i have a bf and he said yes he understands. today he told me he’s 18. making him an adult and me a minor. and he’s telling me i told him i’m 16 when i’ve had 15 in my bio for ages and i told him i’m 15. i’m scared i’m going to be arrested or that he still has that pic of me but he’s screen recorded his camera roll to make me feel assured that he doesn’t have it. i’m reallly panicking what do i do

I need advice. ASAP. I am a person who doesn't know how to say NO, when someone is taking advantage of me. I have a neighbor. She has 2 kids. She only calls me when her kids need me to help them with school work. I've known her for 8 months. She promised to pay for my help, but she paid me only for 3 out of 15 lessons. And she knows very well, I am alone here, I am looking for a job and that there were months when my husband wasn't able to come to me for the weekend because we had no money. It was super hard. She didn't give a damn. Well. to be fair, she did offer to lend me money, which I never would, but didn't pay me for the work I had already done. I don't get it. She is not interested in me, when we talk and I talk about sth in my life, she looses attention after a minute or two. As some of you might remember, my birthday was at the end of April. We communicated on the same day by sms/ text messages. She wanted us to get together for an ice cream or coffee. I told her, I was short of time, because it was my birthday and my cat's birthday, and my husband was coming home from the other side of the country and I wanted to get things nice and ready. But, I still promised to find half an hour to see her. I knew she was only interested in what had happened with me and a certain woman she knows ( I was looking for a job, but refused to take it, because a woman who works there started bullying me even before I had my second interview with her boss. And the bully is my neighbour's older son's private instructor). Now she was curious to get all the juicy details. I found the time, but she cancelled or postponed it for another day. Sth came up for her, I guess. But what hurts is, that she didn't say happy birthday to me. Not on the day,not after,... Not by a text message, not by a phone call, not in person,... It's been 2 weeks. Nothing. She had birthday only 2 months after we met. I was struggling to get by. After paying the rent and expenses, I hardly had money for food for my 3 cats and me. There were days I was hungry more or less. But I went and sold sth of mine and bought her a birthday present and expressed my best wishes to her. Half a year later, I didn't even get a text message for my birthday. NOCD members wished me well, she didn't. Today, just now, she called. She sent me a message she needed me. Her younger son needs help for school and her older son broke or twisted his leg and she needs someone to talk to. OK friends. I've been told, that part of the reason I have developed my ocd is my low self esteem, lack of confidence. That's why people walk all over me. I am there for everyone, noone for me. That's why, people who hurt me, become the focus of my ocd obsessions. One at the time. What do I do now? Do I run to her? Do I offer my shoulder to cry on? This is what my soul, my heart, my empathy tells me to do. But then there is the other side ( call it my ego or just the need for self-respect) which tells me, don't be the idiot she thinks you are. I know she's manipulating me, but since I have never had any support in my life from Noone, I don't have the heart to refuse support to anyone. Please, what would you do? She's waiting for me to call her. I would appreciate your input. I hope someone answers. Peace of mind and soul. Have a beautiful day.
