I'm going crazy?

I was in a relation of 5 years and we broke up 2 months ago but we still talk like a normal friend, not like normal friend but we talk twice a month checking on each other. Recently he told me that he is going out with his friends for trekking. Everything was fine until i started getting thoughts. Thoughts like he found a new girl or maybe he is sleeping with someone. I would be happy if he find someone new but deep down it's bugging me and i'm getting panic attacks and i don't know how to control it. I'm also worried about him because he havn't came online since last 3 days. I want to text him but i dont want to bother him. I'm so flustered and I don't know how to explain how i feel but it's very disturbing.

Thanks in advance.
