sometimes people feel inadequate to help with unexplained illness. maybe your family just don't know what to do or say and feel awkward so they do nothing. i really don't know what's going on with your family but the main thing is that you are in pain and you need help and you want to feel nurtured.

sometimes when people don't think to give that help or don't know how to offer it you need to ask for it. and it sounds like you do need to go to the doctor or some other professional to get all this looked at. 2 weeks without going to the toilet??? that sounds like something that should be looked at sooner rather than later

sounds like your bf is a good support so for now forget everyone else. sometimes people fall short of our expectations. just do what you can to take care of yourself and good luck!
