Childhood aside- my parents are screwing me up in the present. My father less so- so i'll skip in this little spiel. He's just mentioned as the not one to turn to and not helping with my emotional rollar coaster.

Ok the circumstances are: I live alone in an apartment paid by my grandmother about an hour away from my mother and step-father. I understand the whole mothering thing- but when i was growing up my mom wasn't really a mom to me in the traditional sense. But now she is trying to be which is making me angry. And every time i talk to her we are getting in arguments over things which i don't consider her business (since i live alone) or she is belittling/humiliating me about what i love.
The example situation which was this last saturday. i play on her adult softball team and after the game most of us went out to this fast food place- well i was bored since i don't fit in their age group (by like a decade) so i was doodeling on napkins. a member of the team (she's a like a grandma) looks across the table and says "Oh how cute! I wish i could just sit down and draw like that." to which my mom cuts in with (all straight laced and frowning) "It's anime, it doesn't count." Super awkward- to the fact my own mother just "dissed" me in public in front of people we know and i have to see again next week. I wasn't hurting anyone and there ya go.
Anyway besides that she does it constantly where she cuts me down for what i do (mostly hobbies: art, anime, writing, reading)- I honest to god think she is starting to go through menopause and i tried talking to her about it and she bit my head off.
I have my own mental problems that i am fighting- and talking to my mom sets me back to the dark side (in lamest terms)-- is it understandable to want to basically cut my mom from the 90% out of my life?
