I understand completely, it can get very depressing after several months of no flying and no prospects i was in a similar boat, it is very easy to say stay positive but actually living it and experiening it is a different ball game. However, saying that you do have to keep going, keep trying everything, look at aerial photography firms thats where i got my first break. Some will pay fairly well and you'll get some amazing experiences. Apart from that there's very little else one can say other than we're all in the same boat, it's a git of an industry but there it is!!!
