What helps me a lot is learning something new.
Also, support of friends is crucial.
I would totally suggest a therapist, but of course, I understand it can be expensive. However, many therapists nowadays have sessions via Skype or Viber and it is indeed cheaper.
SLEEP! Sleep a lot and eat good food.
And the last one is trying to look at everything from a distance like it is not happening to you, let it be. It is painful now, but you can make through it and you will be happy someday again!
