How to heal a broken heart fast?

I (36f) feels like I have no motivation left, too lazy to get out of bed just because guy I have crush on (38m) suddenly change.

Like previously when my friends try to matchmake him with me, he will always say he still want to be single.

Yet this week I found out he is opening an account in dating app, and match with my other friend. She then give me her account and I chat with him there pretend I am my friend.

The conversation was crazy. Like I think we have same value, same goals, same hobby.

Yet in real life he always like putting up a wall and distance himself from me, hence I got no chance to have that deep talk with him.

This week I somewhat become demotivated and dont want to get out of my bed. Lose my appetite. Got insomnia.

I want to just move on and forget him, be somewhat a normal version of me in 3 days. But I dont know how.
