Hi I am sorry for all you face. First I give you credit and all the parents here who face pain but also raise a family. I have a hard time dealing with myself and can't even imagine the mental and physical impact raising a family has. To me you are not a looser but a strong women.
I am sorry about lack of family support. Do you mean with your husband or outside family? My outside family is not supportive but my mom is so I try to focus on that. If it is your husband can you do therapy together? Can you go to therapy as you stated you don't have someone to talk to about this? Sometimes just talking about the feelings and emotions can help. If you want an email buddy I am here too.
Have you been to a pain doctor? They may work better with you on meds or treatment to help with pain relief that won't leave you where you can't care for your family.
Hang in there and feel better
