I don't want to be any where near my mother

My mother always yells at me when she thinks I do something wrong. When I was little I used to wet my bed often and my mom would sometimes remain calm but if it started happening multiple nights in a row, she would lose her cool and yell stuff like "I'm so tired of cleaning up after you" and "I'm so ashamed of you". Sometimes after her yelling I would be afraid to fall asleep because I thought I might wet my bed again. Sometimes when I woke up to notice that I wet the bed again, I would start hitting my head and think stuff like "I'm such an Idiot" ETC because her yelling would make me feel so ashamed of myself.

I know that my mother wishes the best for me, but her method of scolding me isn't exactly the best. It involves yelling at me for the mistake I made, making me sound like an idiot, talking about how she doesn't do the same mistake as I do and finally after she is finally done she leaves me in my room while I cry all alone. This made me somewhat hate myself and I saw myself as a loser. Because of my low self-esteem I never tried standing against my mother, I always kept my anger to myself.

To make things clear, my mother isn't a monster. She wishes the very best for me and I still remember how she helped me when I was being bullied in grade school. She is always worried about me( she always made me wear a bicycle helmet.)

Eventually I started to rely pretty much only on myself, whenever I had problems or worries I tried to deal with them myself and sometime later I got very confident and started to believe in myself. I finally moved away from my parents house when I was 16(I'm 18 now) and I moved very far away from them. My parents helped me with my furniture and when I we said our goodbyes and I saw them leaving, I felt like it became easier to breathe, for the first time I felt like myself.

These are the things I try to deal with now:

-when my mom calls me. I feel threatened

-when my mom visits my place I feel like I'm stripped away from my freedom.

-I don't feel anything when my mother praises me

-When my mother tries to show me her love like hugging me, telling me how much she misses me. I feel disgusted.

-When I visit my family I don't feel like myself

-When I'm made to go to family vacations. I feel imprisoned

-when she yells at me I start fantasizing how much happier I would be if she didn't exist at all and it makes me cry because I don't think I could achieve such happiness

In my perfect world where everything is fine, my mother doesn't exist

My mother has no idea how I feel about her and I'm wondering how long can I keep this act up. I don't wish anything bad for my mother, I just don't want her in my life
