How can I believe in myself?

Please bear with me. This is long. Growing up has always been different for me. I was born with mild cerebral palsy. I have ADD to. I struggled socially. I realize now that a lot of people looked down on me. People where telling me I can not do things. It started in day care. I could not even go swimming, or bowling with the other kids. Nobody even believed I would be able to swim. I swim pretty good now. Even my mother told me not to use a stove, or drive a car. My family always treats me like a kid. I am almost 25 live with a roommate. Yet during family gathering everyone 21+ gets offered alcohol except me. I am the only one who seems to drink responsibly. Even my teacher told me that My dream to be a veterinarian was stupid. She said I would never be able to. My step sisters always got favored. I got yelled at for not soon chores, and they got away with not doing theirs. I was always treated like a bad kid. Got in trouble for things I did not do. My step father always hated me, and manipulated my mom into neglecting me a lot. Now I have anxiety disorder. I feel very lowly o myself. I do not even feel like I can do anything. I just sit at home: I do not even think I can do good if I get a job. I saw a counselor, but it only helps some. I am not sure what to do. I am in pain a lot, and my health sucks because I have lack of desire to even try. I am starting to feel tired of being pushed around. I have had times where I have wanted to yell at family members, but I stop myself because my mood stabilizer she'll me control it. Has anyone else been through stuff like this. I so give me advise.
