Devastation

Hey.. I'm azan, I've had anxiety for a long time.. just being insecure about even the smallest thing.. for example, that day i went out wearing a t shirt but i got so ashamed and insecure of my body that i started getting really nervous around people and i rushed back home to change.. and now i just went through a break up.. with the person i loved more than anything.. it's been 2 years we were in a relationship and it all came to an end just like that.. I'm so devastated, my heart beats so fast right now i can't calm down.. I've been breaking down every 2 seconds I'm nor distracted.. it's so hard.. i can't move on .. please.. someone help me
