I felt the exact same thing. What did I do ? I adopted a puppy from the local pound.

He made me get up and take him out. He makes me take him for walks. He brightens my day. He's always happy to see me, he is my Emotion support animal

Some people just can't have a pet for housing reasons of course ... my daughter found a half dead kitten in her apartment complex. His name is Cosmos and she's so happy she kept him once she nursed him back to health.

I have no physical friends to do stuff with , I have some great friends online.

Maybe foster a pet?

All I know is my dog at times literally keeps me half way sane.

I'm sorry you're hurting so much (((( hug ))))
