I used to feel very similarly to how you're feeling now. I quit college after a few years as well. It wasn't me. Seeing all my friends graduating and going off in many directions in their careers made me feel like a loser. I felt stuck and I was still living at home as well. Keeping all these negative thoughts to myself didn't help either. I felt like I didn't have a future and I couldn't get anywhere. I didn't make a lot of money either or any at all.
What changed was the support I got after I opened up and shared my insecurities. It changed my perspective. You are still young and even after 5 or 10 years from now, you will still be young. You still have many opportunities and whatever your body may look now or however you feel about it, that can change too. Whatever path you're on right now isn't a path to destruction, it's redemption. It's a underdog story. It's a journey where you'll eventually reach a place you're content and happy with. Don't let anybody else bring you down, not even yourself. For now, set a goal. Any goal. And keep making them, even if they're just minor goals. I had a hard time working out so I set a goal of at least 10 push ups a day and it made a huge difference. Some people might not see that as much but their opinions don't matter.
You go at your own pace and it doesn't matter how slow it is compare to others, as long as you're moving forward every day. Let's start with that. And you know what, I'm proud of you for reaching out for help. It's not easy to do so. And I have contemplated and attempted suicide before, I told myself I would only do it if there isn't anyone who would feel sad about it. Believe me, there's always at least one and if you don't have that one person, I'll be that one person who'll be sad if you do that. And honestly, we need more good people in the world. Don't let that town of racists destroy who you are.
If you need someone to chat with, you can send a message my way. I don't normally comment but your situation resonated with me. I hope this helps you a little bit.
