I feel like a bad person

Honestly I’ve never felt like the worst person ever , all my life I’ve always struggle with fitting in and making a good friend group, and I always think I don’t do enough for anybody and sometimes when I feel like somebody is becoming cold or distant I make sure to keep a distant too out of respect or a mechanism to help me not feel hurt , as a result a friend of mine did this and I stayed away because I had no idea what she was going through and my other friend who I’ve met at the beginning of the year I’ve never had a good feeling abt her because I noticed her starting to be really flirty with my boyfriend and when I tried talking to somebody about it , she twisted the entire situation to her assuming I was sl*t shaming her, which I’d never do that is not in my dictionary , so when I arrived to school everyone said she was saying really bad things about me and what’s worse is that she did this two months ago and I found out last week I cried to all of them about it and they ignored me they all laughed and just left me there to cry , I tried talking to my friend who slowly grew distant instead I noticed her getting closer to the friend who wronged me . I noticed all my friends growing a distant , I slowly felt like I failed as friend and then I slowly starting convincing myself i was a failure in general , so as a result, I turned to marijuana and cough medicine, and multiple dealers reach out weekly so I can buy more stuff , and what’s worse is that I know these people are not good friends but I still let them get to my head and on top of that I resort to substance abuse to help with my overthinking and anxiety , I need advice

I feel like if I spend time with anyone im always failing everyone else. A lot of people depend on me and want my time. I feel like I can't be enough and it makes me feel like I deserve to be alone. Does anyone ever feel like this?

I'm just venting, but everything is feeling so overwhelming lately. Every day, I still find myself checking on my ex. I know it sounds obsessive, but it’s not coming from a weird or stalkerish place. It just feels like I never got closure, and I’m stuck in this loop. I read that “closure is a choice, not a conversation,” and I try to believe that—but part of me still needs to know what he’s doing, like it gives me some weird sense of closure, even if it’s just temporary. And I hate that I’m like this. On top of that, I’ve been wanting to see my Pap, who is in the hospital in pretty severe condition but I never have time because I’m always working. My job is stressful. I try so hard, but my grooms don’t turn out the way I want, and I just feel like I’m failing. Then there's my financial situation—my car payment is $713 a month, plus insurance and other bills. I can’t save at all. Thankfully my mom pays the rent, but she constantly holds it over me and threatens to kick me out. It’s never felt stable at home, and now it’s worse. Lately, my childhood trauma is resurfacing, and it’s affecting everything—my friendships, any chance of a relationship, even my bond with my pets. I feel like I’m falling apart, and when I finally get in bed at night, I just feel hopeless. I look around and see people I went to school with thriving, and I feel so far behind. I used to feel ahead because I was already handling adult responsibilities, but now it feels like I’m stuck while everyone else is moving forward. I’m losing control of my emotions—randomly lashing out, struggling with anger—and I can’t afford therapy or even regular doctor visits. Sometimes I can’t even afford groceries, and it’s frustrating because I work hard and still feel like I’m drowning. I just want a simple, peaceful life: a modest home, a normal car, a stable routine. I want a support system. I want to feel connected like my friends Jessica and Ashley, but I don’t. It’s just me, but it’s still lonely. It feels like no matter how hard I try, I can’t get anything right. Like I’m always doing something wrong in someone’s eyes, and I have no one to turn to for help.
