I agree DOCTOR first and second-let yourself off the hook!! You are responsible for YOU! You can not be responsible for everyone and everything around you--the world will not stop if you don't do this or don't do that for someone else.
DO or NOT DO because you want to or don't. It is OKAY!!
Families are always in motion- evolving- likes & dislikes forever changing---it is the way of life--let yourself believe that.
The best thing would be to see a dr., maybe he/she can help you get on an 'even keel' and life may just look a lot more managable--ask me how I know!!! ((pm's welcomed))
all the best to you,
Susan
