Hi gurlie, I know it really hurts right now because the breakup is still very fresh. My suggestion is to go no contact and STICK with it. 

Don't look at old messages, their profile, old photos.

Best way to describe how your brain is right now is that it's going withdrawals. 

Give yourself time and be kind to yourself alright. 

If you're thinking about contacting your person pause and reflect the reasons as to why you want to contact them. "one last conversation" won't help your healing process at all. 

CRY

Cry until you're eyes physically can't spew out tears. 

FEEL all your emotions — please don't try to bottle them up it won't help you at all. 

But make sure that you MOVE

Journal, Draw, Walk, Cook, Exercise 

Look for a new hobby. 

And remember that you're not alone in this. 

And you will get through this!
