Work & ADA Discrimination?

Does anybody else have issues at work BECAUSE you disclosed that you have Bipolar? I had a major manic episode about 6 months ago which is why I went to the doctor and got diagnosed.
I was having trouble concentrating at work and then I started using my work computer to find guys to have sex with. I sent explicit photos to them and I called off work to meet with one of them and go to the casino. I didn't care at the time but after about a week and a half I felt guilty depressed and ashamed. I told my employer what I did and I said that I just wanted to be honest with her. I told her that I needed help and I left that day to see my PCP for bipolar meds. The doctor also discovered that I had low thyroid so I starting taking thyroid meds too. Turns out that I have nodules on my thyroid and I have hypothyroidism and of course Bipolar.
Soon following I was able to get a real diagnosis from my psychiatrist and I started on some other meds. The doctor wrote a letter describing my condition. I gave it to my employer. I was seeing him and my therapist once a week and taking off a lot of time from work. I use my vacation time as I get it (like 3.5 hours every biweekly paycheck). My son is autistic so I also use a lot of time for his appointments and going to school meetings. I asked my emplyer several times about FMLA for him and now also my diagnosis. My HR rep said not to worry about it.
Anyways, I told my HR rep that I need special accommodations because of my diagnosis. I discussed my symptoms and we decided that I would get a private office to work. This was fine with me until I saw the room. It is a glorified storage closet with a desk. The lighting in there is one florescent light and no windows. It is cramped and people come in and out as they please to get things from storage. We also discussed other accommadations such as flexible schedule.
My direct supervisor now ignores me and it is very uncomfortable being in the same room with her. She hired me as her assistant but she doesn't even talk to me. Another department needed help with a project so she told me that I would be doing that work. I started wandering if my job was still being her assistant. I really have no clue anymore what I am supposed to be doing. I was assigned a portion of the project from the other department to work on by myself while others in the project work together. I am not invited to the meetings that they have on the project. I feel like I am being singled out by everybody in the office. I don't want to tell my coworkers about my bipolar, but they wander why I get an "office" where nobody else does and they act like I am privledged.
I told my HR rep that I am still having trouble concentrating and focusing at work and that I get very anxious, even fearful sometimes, about traffic on the way to work. People drive like crazy maniacs and I get super road rage about it. So much that I start driving reckless. I have been in a few fender benders on my way to work so it makes it 10x worse. I am late every single day. As one of my accommodations I can come in late by an hour without calling in. After an hour I have to call, but nobody ever said anything to me about being 4 hours late a couple weeks ago. I assumed that I would get reamed out for that. Anybody else would. I don't want to be treated differently. I just want certain things that would help me perform my job.
To avoid most of that mess I suggested that I work from home. There are others that work from home in our office so I figured that it would not be a big deal. The HR rep told me that they cannot allow it because they don't have any equipment and because of HIPAA laws (I work in healthcare admin). She said that they wouldn't be able to ensure security of protected health info if I were to work from home. I don't understand why none of this applies to the 13-15 people who currently work from home. Two weeks ago a coworker was planning a vacation and they gave her a laptop to take with her and paid her overtime to work a few hours on a timely project. When she returned from vacation she kept the computer and now she works 3 days a week at home. How is it that she can work from home and I can't?? I used to love my job and now I HATE it and I cry to my boyfriend all the time about quiting, but he always convinces me to "keep on keepin' on"!! I hate it!!
My sister is saying that this is ADA discrimination, but I don't know anything about that. Can someone please give me any feedback that you can about my situation.
Thanks for reading my long first post!

Hey there Heatherbug!

I'm not sure I can answer your question about discrimination, but I can certainly empathize. I am full time and recently have made a request for some 'accommodations'. I have been there for a year and not asked for anything, but I've been really unwell and now think I need a bit more flexibility and support. I have a meeting with human resources and my manager next week to discuss these accommodations and formalise them. At the moment I am sort of forced to ask for special permission to do the same things that my colleagues take for granted. Everyone has flexible working hours e.g. 9-5 or 7-3 etc. Everyone works from home for 1 or 2 days per week, my bosses, my co-workers, and the people that I supervise! Yet if I ask for either of these things occasionally for whatever reason, I get questioned about why! I am hoping we can clear some of that up at this meeting.

In terms of thinking about whether it is discrimination, I would get some legal advice and tread carefully. I got advice from a voluntary legal service a few years ago regarding discrimination and they were really helpful. I didn't pursue the case in the end as it would have put too much at risk for me, but it was good to know the ins and outs of the law and where I stand.

Best, keenie
