Guy, 20, never was in relationship.

Few months ago I really got into redpill/blackpill content, I was reading and watching this stuff all the time. I never really believed it to be 100% truth, I was like "It's kinda bullshit but I guess you can learn few things", well, no. Before that I wasn't really happy with my life, I was already quite depressed but at least I wasn't so concerned about relationships, I thought maybe it would happen someday, now it's really fucking bad. I have so many negative thoughts about me and my future, I feel very lonely, I am worried I'll never have a girlfriend, redpill really made me feel hopeless. Nowadays I don't believe any of the things they say, I try to look at more positive content and avoid redpill bullshit, but I don't really seem to get any better, I think that damage was already done. Everyday for past few months I felt like total loser and worthless trash. I never had a girlfriend, I can't get a job, I lost almost all friends, I don't even have anyone to talk to, I don't know how to meet new people. Most days I stay at home and try to pass the time, there is nothing to do in shithole I live in, I try to at least do something useful, I exercise pretty regularly, I help my parents with everything I can, I try to study something, but it feels so irrelevant, like I am not doing any progress at life. I recently applied to college, I feel like it's my last resort, maybe there I'll make some new friends and find a job, but I highly doubt it.

How can I get out of this negative mindset? What I should focus on? Please tell me if you have any advice, I can even provide with more detail if you want to understand my situation better
