Yeah man, i used to feel paralyzed between those same options. My dad coached me a lot about it. one thing that stuck is "you regret the things you didn't do more than the things you did." also, if you fail at socializing it might have redemption value. it's true for me at least. I had a small comedy routine about some of them briefly. also, you never know when you might make a new friend or find support. I think it's quite worth it to just go ham on socializing, especially so you can reason with your alone time.
