It's it worth it to try to make friends when you are a NEET?

So I'm a NEET and like most of you, I have also dealed with depresssion, bullying and isolation. Relationships are pretty hard for me, since I'm always feeling like I can't connect properly with other people or that they are secretly hating me. Which is why I have spended the last 7 years without contact. But I'm also a human being, and socialization is important for humans... but I'm conflicted because I'm afraid of messing up things again. My sib used to be my only contact, but lately they are very distant with me, and they seems to care more for their own friends...The relation with my family has always been complicated so I'm pretty alone all the time... Should I give it a try to make friends or should I just accept that I'm going to be alone forever? Does anyone feel like this? Give me your most honest answers according to your experiences.
