What do you want for yourself? Disorder or no, we adults become responsible for our own paths, we get to choose what or whom to include along the way.
It's not nearly as important what others think about your prospects as it is what you yourself do about them, YOU have to live your life, I suggest you live it passionately. Many of us rose up from meager beginnings, apply yourself with stern purpose, and you might rise also.
Tiger and Zed have given you excellent answers. I hope you take their advise seriously.
I understand your position better than you may think possible. Get revenge. This is how to do it: Become more successful than either of them. Don't talk to them anymore about your personal life. Shift your thinking over about your disorder; make it more of an occasional inconvenience, rather than the focus of your life. Never forget or refuse to take your medication
Get a job, be on time, never fail to show up, and be polite to everyone you work with. Help them. Earn promotions.
You don't say how old you are or what your disorder is. I could be more specific if you had.
But you need friends to take the place of your family relationships. Stay in touch with your family in a superficial way. I hope you are able to move out as soon as possible.
All of us children have to learn to stand up to adult and survive. This usually happens when we are growing up and it's really part of the job of the parents to facilitate that happening.
There has to be a healthy separation of a child from his / her parents as well. That become extremely difficult if the parents have not sufficiently affirmed what the child has become and even harder if the parents are still putting the child down---which is what those low expectations are doing to you.
And frankly, they are not good parents; and they are justifying their parental failures by continuing to hold you in low regard in their own minds.
In other words, everything---including their poor parenting skills---are your fault, not theirs.
Talking to a counselor would be a good way to develop a plan to get out of the terrible box that they are trying to keep you in.
You need a plan going forward and you could certainly use the support a counselor would give you in determining the details of that plan and supporting you as you implement it.
Yes, what Tiger and the Z say is correct; but you will be able to do that much more easily when you don't have to use so much of your energy dealing with the constant pressure of their negativity.
