How to get rid of these thoughts

Since everyone has given up on me and I can’t seem to figure out why I have done nothing wrong or almost nothing, and speaking to my psychiatrist a little & mom they agree twas other people who chose not to hang out with me for reasons I don’t really understand, I have started giving up on everyone else who MAY have wanted to get to know me or do now. I don’t wanna bother with anyone but in the end of the day I hate being alone. I have oficially given up on school 2 a long time ago although that wasn’t entirely 2 do with friends, the education offered at the college I’m at is very low and I’m doing a degree I know no matter how much I try I can’t finish because it’s not my kind of lessons & even if I get it I won’t use it later when looking for a job. I thought earlier on this year 2 apply 2 some universities elsewhere 2 go into something I’ve wanted 2 for some time & know I’ll be much better in & will do it no matter what but dad wasn’t ready 2 let me go & I was ok with it because I know why he wouldn’t let me go (a problem I had in the past). Now he sees the education I’m getting sucks & I have no future here for sooo many reasons & wants me 2 go so I’m waiting 2 see if I got in. But the problem I had in the past & he wouldn’t let me go was I tried 2 give up on life by taking some pills, wasn’t successful, that feeling is still with me everyday all the time. Not gonna do anything about it because I wanna get better & get out & get the education I want away from everyone here but don’t wanna hurt my parents most of all like I did the last time but what if 1 day I just do something like the last time & worse? How do I get rid of these feelings & thoughts? My psychiatist just asks me if I think of these things, doesn’t answer much advice 2 this.
