Exhausted of people..

I'm exhausted of people. It's to the point where I'm isolating myself because I don't want people in my space. The people I did let in showed me why I shouldn't have let them in at all and now I'm closing myself off from people.

I recently came out of an emotionally abusive relationship and I'm so exhausted. All the effort I gave just for it to be shoved back in my face has me really drained. I was feeling tired of people before my relationship and now it's worse especially since I was feeling like this when I met my ex.  Simply for the fact that I find myself giving more effort in friendships and relationships than others give. Sometimes I message friends and when they talk it's all about themselves. Some don't even ask me how I'm doing. Other times when we're chatting they would leave the message and update their Whatsapp status or post on IG or SC and won't reply to me until hours later. By then I'm so turned off the conversation that I don't reply at all or just give a reply to end the conversation.

I'm so damn exhausted and tired of people like that. I don't know if I'm protecting my energy or just really staying away from people and I think it's getting worse.

Has anyone ever felt like this? How did you get over it?
