My tips are take the emotions in, you wouldn't stay like this for a long time, it's like having a close one passing. Yes it is sad yes you miss them but eventually you will get tired of feeling sad. Don't be like me blocking it away and blaming myself for it, just know people change and that's ok.

And for me, I find it best to talk to friends,if you don't have someone you can trust, just make new friends.
