One usually causes the other, sadly

It’s a toxic cycle. Depression makes you wanna isolate, which causes loneliness, which can also make you wanna isolate the stronger the loneliness becomes

I deal with that a lot.

One key tactic that I learned significantly helps as well is to stay out of your head and that can be more difficult for some than others
