I went through my first break up about 6 months ago. My ex and I decided to remain as friends. We contact each other on a near daily basis. But whenever he stops contacting me, I start to over analyze the situation (like is he seeing someone else?). Since the breakup, I been waking up to panic attacks in the middle of the night - especially on days where he doesn't contact me. I don't know why I feel this way since we are just friends. Anyone went through something similar and can provide any advice? Thank you!
