Shanari, please don't get discouraged with life because of your Mother, sometimes parents may get egotistical and I know this from experience.
My mum is a complete Bwhat and I happen to don't see her as often as I should, but thats ok I still love her in a conditional manner.
My father can also belittle me but I can also do the same, his support is great and I do appreciate it. But I know what you mean, I get really angry when people condescend me as I have spoken to Karen about at one stage because it was starting to really upset me.
Unfortunately in life, everyone is different and has different point of views and personalities, don't feel worthless because you are not.
People all around the globe don't get along with their parents as best as they would wish, but thats ok because keep in mind this will only back fire when they want support when they are older.
You have other family, maybe your brother perhaps? So you are not alone, please don't let trivial crap get to you as I know it happens in my family yearly.
Be the bigger and stronger person and take control of your life, whether that be getting a job and moving out and enjoying life.
There is alot of exciting things in life I would like to see you experience, please don't think of throwing it all away because there are positives in this life that keep us going.
Love from Australia
