What to do now

So I have finally decided to leave my boyfriend since our relationship was not working at all and I was just unhappy the whole time.

But now that we don’t speak anymore I feel so lonely and a bit depressed.

Idk what to do now on my spare time and I don’t know who to talk to anymore. I tried reaching my closest friend but she’s always busy and that makes me feel even more lonely.

I feel like there’s a whole in my heart which makes me feel empty and it hurts.

I’ve been crying lately to let everything out, but I just don’t want to keep crying and do nothing because being lonely makes me reminisce the happy times I’ve spend with my boyfriend and that’s even worse because I will start to miss him and start regretting breaking up.

So anyone has any advice on to what to do?

I just want the pain, the loneliness and the depression to go away
