You’ve been posting the same question for the last two years. Understand this: you aren’t a failure. You are in the wrong place.
I’m sorry if this sounds mean, but honestly, you don’t seem to make attempts to take the advice you’ve been given, though it is good that you run a club. Your college is not a fit for you. As far as I recall from your posts, you seem to have not tried other avenues to meet people, such as getting a job or volunteering.
I think @Publisher has good advice.
As far your “friends and acquaintances” of your parents, do you mean their friends? Ignore them, or be honest and say “I’m just there for the degree.” Meanwhile, I encourage you to continue therapy.
It’s been said already, but I’ll say it again. College isn’t always the best four years of your life. I went to college and made zero friends. All of my friends were from work. You really need to understand that what’s happening now is not going to dictate the rest of your life. People outside of college are not going to bully you. I do think you still have a bit of high school mentality and it’s time to cast it away.
You’ve made the decision to stick with this school. So now, just get through it. That’s what plenty of people have to do in life. Eventually you’ll be working and living somewhere where no one is going to know or care that you hated your college.
In the future, it might be good to use your college experience as a “what not to do.” You’ve known for years that your college isn’t the best place for you. So if a future job makes you unhappy or you don’t fit there, cut your losses and move on. There’s a place that’s right for you. You don’t have to settle for being unhappy. Good luck.
