Hey. I am in a similar spot to you atm. It sucks. It is hard to be positive when things aren't going well. I'm not putting on a brave face at the moment, I'm wallowing. It sometime helps - like in the movie When Harry Met Sally, when Billy is upset and he says he is just going to moan for a while, then proceeds to lie in bed and moan out loud (much funnier than it sounds). It can be cathartic. I moan, wail and cry, like some some of our indigenous people do at funerals. It helps stop internalising the anguish, pain and lonliness.
