Pregnant and working?

I posted something earlier today about being discriminated against in my workplace in many ways and most people said "walk out" well that is not an option for me... I need the money, insurance, and the reference. I am planning on quitting after I get my maternity leave pay and finding a new job, but for right now this is unbearable!! All I do is cry at my desk day after day. These people are just unreasonable and crazy! My mother actualy works here in HR and doesn't agree with anything these people are doing to me, but can't speak her mind because I am her daughter. I am going to see a therapist about this. I want to be told to leave work and go on short tem disability. How can I convince her that I need to, and what would you all do in my situation? I just want out... I don't deserve to be told that my hair is this my clothes are that and that I can't put up my 3d ultrasound picture because it looks gothic... its just not fair to me.
