Anxiety

Hey, I don't know how this works, but let's try it. So, I've been dealing with anxiety for petty much my whole life. Recently, it's gotten worse. I was involved with a guy 4 years ago and to this day, he continues to mentally harass me. He is a dangerous person. Although, he has never hurt me physically, the mental abuse was just too much. Every now and then, I get follow requests from his acquaintances. They spam me from different account. At this point it almost feels like it's a guilty pleasure for them. As soon as I see these notifications, a rush of anxiety goes through my whole body and for a minute i feel like i can't breathe with an ache in my chest. I've gotten better at controlling it, but it's still suffocating. I feel trapped. It's been 4 years now and 2 years since I decided to cut off everything with him and it still comes back. When will this end?
