My heart is breaking. My body feels like it is electrified but worn out. My soul aches.
This is a good way to describe one of my breakups with my ex. Feeling emotionally burnt out and the body following suit.
Just because you go through this process doesn't mean that you'll be alone and nobody will take care of you forever, though I understand that it can feel that way.
I'm interested to hear what other's suggestions are, but for now I would consider looking after yourself. When someone suggests this to me, I still wonder what that means--an easy way to think of it is to imagine you're your best friend, and you're making suggestions to him. The idea is that you don't sink into negative places to the point where it harms your decision making. Do you keep any hobbies?
Also,
these ideas will help you with self-compassion which I think is very important during these early days.
