A strange obsessive feeling

Hey, I've been feeling this weird urge lately. I want to hug the whole world.

I feel like I want to hug every person on earth, every person I see, every post I see from someone. I have a strange heaviness in my chest and a melancholy that I cannot give love to the whole world.

I feel like something happened to me. I've been through a lot of stress in the last few months, but now I suddenly want to forget about those who hurt me, erase them from my memory, and hug everyone else.

What's happening to me?
