My chest gets uncomfortably tight whenever I think about myself being lonely

I find it to be really hard to connect with people. I only have 1 in person class this semester and it has been a social nightmare. As for my workplace, there is just something about not being able to be friends with people from there, maybe because of the age gap.

It has been really lonely for the past 2 years. Ever since leaving the army, I have become socially inept and I find it hard to relate to anybody. I’m not that old but I also don’t really know how to make friends. Any tips?

Thanks. Being lonely feels like absolute crap
