It sounds like you may have quite a few separate issues going on. None of them sound good and really need to be seen by a doctor.
How serious they are is not something that can be answered without being able to examine you and run blood tests at the very least.
We aren't doctors either,
I would suggest though, that you might want to try and find a clinic that you could go to, one with a sliding scale fee set up and if your pain is so extreme that you can't sleep you just may need to go to the emergency room, especially with the bruising all over your legs and that bulge that you feel in your stomach.
Good luck
