i feel like i did something irredeemable and it’s driving me crazy. idk how to move on i feel so bad

i don’t know what changed, but in the past 1-2 weeks something switched in my brain and now i am obsessing over every mistake I’ve ever made, and i firmly believe the guilt i feel is justified. i am a pathological liar and i’m realizing i may have lied about more things than I ever intended to. i think i tricked myself into believing some things and now I feel awful that I’ve lied to myself and others about so many things. my mind is a mess and i can’t even tell what is a lie and what isn’t anymore. i also feel like i’ve been taking advantage of my boyfriends family who has financially supported me for these past few years, because i had convinced myself and everyone around me that my physical health & mental health was worse than it actually was. i never meant to take advantage or hurt anyone, but i can definitely say that i became complacent and comfortable living these past few years without having to worry about work, school, or really anything. i think i used “not feeling well” as an excuse to not do anything because i was too afraid to leave the house and function in society. i feel so awful and disgusted by my behavior and the guilt is eating me alive. i even feel bad using my phone because they pay for it, and feel bad being in my apartment for the same reason. i feel like everything about me is a lie and they’ve been paying for and supporting a person completely different than they thought. maybe i’m not who I portrayed myself out to be at all. i’ve felt so disgusting and so awful i can barely stand it. this morning i woke up feeling like i was suffocating, my chest hurt so bad and i felt like there was absolutely no way out. i really felt like i was dying. other than the lying, i’ve felt awful about things i did as a child where i didn’t know any better, or i even feel bad about my own thoughts and emotions that I have no control over. my mom says i’m being too hard on myself, and that i can’t help that i lie, but i don’t believe that. i think i deserve to feel this way and that i’m not being hard enough on myself. i lied and took advantage and therefore i deserve to suffer. i caused people to worry for me when it wasn’t necessary, when i was fine. i deserve to feel so guilty that i’m nauseous, i deserve to feel ashamed. i feel like i don’t deserve to eat or feel better, even though i desperately want to. i feel so guilty and so shameful i literally can’t function. i want to escape this feeling so bad, i want to get out of this guilt that’s keeping me from moving on and improving myself. i acknowledge that i have a lying problem, that it’s a mental illness, but i am ashamed of it and feel disgusted that i’m this way even though i can’t help some of it. i truly don’t know what to do or how to have compassion for myself. probably a good idea to share that my dad is a pathological liar and never received help, and i’m pretty sure i learned this behavior through him. not to mention all the stuff i did as a kid that i feel bad about, or the fact that i feel bad about things i can’t control. and i even feel bad about finding certain things funny. the guilt is killing me and i don’t know how i’m ever supposed to become a better person if i’m so sure that i’m undeserving of ever feeling better. in my head i truly feel like im a monster. i feel like i’m having a crisis because i’m realizing i lied about a lot of things without even really realizing it. or i deceived myself into thinking things. and I’ve lied about things for sympathy, for attention, to make myself seem more interesting, or to make me seem less pathetic than i actually am. i’ve lied about some serious things, and i’ve lied about things that don’t matter at all. i don’t know how to keep living. i want to go home to my apartment and be in my safe space, but i feel disgusting being there when i’ve taken advantage of my boyfriend’s family, even though it was never my intention. no matter what I do and where i go, i feel wrong. because i’ve done so many bad things and i can’t forgive myself. i feel so morally wrong i can’t stand it and i don’t see things ever getting better. i feel like I’m going crazy and i feel so alone. i can’t escape this guilt no matter what. and i feel overwhelmed because I know this isn’t something that can be fixed quickly. am i ever gonna be able to live without shame ever again? am i ever gonna be able to do the things i love again? the things that brought me comfort? nothing brings me any comfort, and i spend all day in bed or sitting around doing absolutely nothing because i can’t distract myself. i can’t stop thinking about all the things i’ve done no matter how hard i try. i obsessively read and look up online things to try and find reassurance. i feel like i’m going crazy. and i just feel so sorry. to everyone. and i’m so extremely ashamed of my behavior. i can’t stop obsessing about the past, the present, and the future. don’t i deserve to feel this way when i’ve lied and done bad things? even if it wasn’t my intention, or if it’s a result of a mental illness? don’t i deserve to feel debilitating guilt when i’ve been a bad person? even though i know i never had any bad intentions, i don’t think it matters. am i gonna feel this way forever, where everything i do or everywhere i look, im reminded of the the things ive done?

I did post about this the other day, but I’m just genuinely worried like this happened many years ago and I can’t really remember exactly what I said, but I have a feeling like I said something really mean and I think I lashed out on a person like a stranger cause I don’t know I was probably going through something and I’m afraid that like it was so bad it caused them to hurt themselves and now I keep thinking like what if the police are secretly looking for me because the harm caused, even though I have no evidence of any of this, but even this Happened like a deca ago, it still haunts me like I really hope that the person is OK and I constantly like keep reviewing like their conversation over and over again like in my mind like I genuinely feel like a bad person maybe even a criminal 😃

i’ve done so many horrible things and i’m just so scared that i don’t deserve anything good in life
