I'll start chipping in now cos I've got a good feel for the direction you're sitch is heading,we've got a lot of work to do on you to get things under control but I'll chip in where I can.
Next thing, it's probably best to keep just one thread running otherwise you'll have bits of info all over the place so I've posted these bit here.
These will give you an idea of what you will go through. But don't worry if you get yourself in shape physically and metally you'll get through all of this.
