I was going to ask are your family narcissists.You can't get on with them if they are,they don't care for you or let your feelings matter or count.They only have you around to meet their needs so long as they get what they want from you,and in the process of making sure you are around to cater to their needs they need to run you down, take away your self esteem and make you dependent on them.I became a lesser being,my identity lost,my strength gone,I was living in my sister's shadow she was making me physically and mentally ill.Go no contact while you have your physical health and some sanity left.Or else they will take it all and literally leave you for dead!
I feel for you I really do!
