<human>: I[f21] broke up with my boyfriend[m19], we were a couple for 18 months. It was the right desicion and I liked being single, but...

A month later I fell in love with a friend[m21] of me ánd my ex. He turned out to be in love with me too. We dated for two weeks and then he broke up with me because my ex (still his friend) had troubles with it. Once my ex is okay with it, we'll get back together.

He made a brave and good decision. But it's hard for me, I was happy single and now I feel broken hearted and there's nothing I can do to speed up the process (although are my ex and me trying to be friends). 
Me and my "crush" are both people who hide our feelings, pretend to be strong, so he doesn't know how I feel and I don't know for sure how he feels. I'm willing to wait for years for him, if I have to. But I feel so bad, I can't eat, hardly sleep and have trouble focussing. 

Is there anything I can do to feel better?

Can you condense the text into three sentences or less?
<bot>: Until my ex gets over me, I can't be with the one I love. What do I have to do to feel better while waiting?
