hi, pretty new on MN, just looking for a bit of advice/sympathy.
back story: i'm 25, have a 7yo son, split from his dad when he was 6 months, i have a partner who doesn't live with us (we were together from when DS was 9m-4&1/2, got back together last august)
went to uni for 4 years doing psych while working 2 jobs, realised i didn't want to do anything to do with psychology, worked in admin for the NHS part time for a year, last year did the PGDE and now work as a full time teacher.
OK! so. my problem is with my family. my mum is a teacher and my youngest sister is training to be one, my dad and other younger sister both work within the NHS. my mum and dad were married young and had me in their early 20s. my mum has always been of the opinion that when i got stressed about dealing with everything (i had LO when i was 17) i was "just whining" as she did it all when she was young too (she had me at 23, was married, lived in a bought house etc - just much more stable).
i feel like i've done really well for myself and my dad always goes out of his way to tell me how proud he is of me 
however my mum and my sisters treat me like crap. everything i do is wrong, down to the way i dress and the places i go. i am NEVER a good enough mother/daughter/sister/teacher, constantly get everything i say picked apart, screamed at in front of my son, cannot relax in their house at all anymore.
they love my son though, and they help so much with childcare. my mum works part time and looks after him mon & tues before & after school. they're also pretty generous with taking him for a night at the weekend. they've said though "don't move to canada or anything to get a job... i mean well, YOU could go just don't take DS away from us". i don't know if they really have no fucking clue how much they hurt me or what, but every time i'm at their house i leave crying.
i know i'm by nature pretty sensitive but i just want a bit of support or a hug every now and then. my sisters get on really well with one another but both look at me like i'm a piece of dirt. it's got to the point where i doubt that i'm actually a good/nice person and maybe i am just completely crap.
i don't know what to do. my mum is v strong willed and there is no arguing with her. i try say to her "don't speak to me like that" but it causes a HUGE row, slamming doors, refusing to look after LO etc. what do i do? :(
