I need constant attention from people. I'm feeling very alone and left out. I love my friends. But I get very jealous and angry if I know they planned something and didn't think to invite me or include me in a conversation. 

I want to download tinder again so I can talk to people.
 I'm feeling very lonely. And like I need more friends to talk to. Idk...

My therapist says that, since I broke up pretty recently, I should focus more on friends and family, however I'm feeling a bit distant...

How do I cope with this? How to be alone? I have hobbies, but I'm not really enjoying them.
