How to deal with professionals and others who patronise you and treat you like you are disabled

I have had many professionals treat me as if I am dangerous, an idiot, intellectually disabled or just plain strange. I now have a good doctor in a private practice.

 However, people who I have not disclosed to also treat me this way due to misunderstanding of my social anxiety and nervousness, which they think is shyness and lack of confidence. When people treat me like this, I feel hurt and over sensitive and even begin to think I am stupid and can't do anything.

I have tried to hold down a job while still experiencing symptoms, however, people say I am incompetent and lazy and slack and forget little things, even though I am giving it my all. It takes more effort than most people for me to hold down a job. Even getting into a routine and being happy takes effort for me.

Even people I mix with tend to take advantage of me because they can sense I am not feeling well and get me to do their work for them. I had a woman at college insist on me doing her college work for her. I tried to say no, but she said she cannot do it herself. She even cheated on my entrance exam. Because she was so nice to me and crawled to me, I did it.

It took a lot of work to do two lots of work and she was bragging about how smart she was and how well she was doing. It ended up I could not deal with doing both and quit the college course. She said I am not doing anything, I can do her work for her. I tried to say I needed a break, she said I am not doing anything. She wrote no notes and I was confused about what was required of me, but I tried to do it with the knowledge I had and she got it wrong and blamed me.

She then put me down, saying I cannot work, I do not work hard and that I am overweight and why can't I get a boyfriend. I have not seen her or heard from her in a year and figure it was because she does not need me anymore.

Does anyone else feel they are being used by people, often not realising it until too late. Of course I am naturally a kind hearted and generous person and am very good academically. I feel she realised all this and took advantage. Other times I am taken advantage of too when not feeling well. When I am well, it does not seem to happen, why is this?

For instance, two men at a party had me in a corner and had their hands all over me. I was too scared to tell them to stop and once I was well again, they did not come near me. I can't understand why someone who was well is less likely to be used and when someone is not well, people can sense it.

Another example, when I was really unwell, before I was diagnosed, I apparently gave all my money I had in my account to my parents to pay bills and buy groceries. I would do this willingly,even now as they do a lot for me. At the time, however, I did not realise this.

Once I took my medication, I asked why I had no money left. Why are people more likely to be taken advantage of when they are unwell and to be conned into things? How do people sense this in a person? I always wonder about this.
