Jack, I am not in TX, but I am in a very similar situation in VA. I have BPD (with alcohol abuse). I am a new nurse and I am in HPMP (the VA equivalent of TPAPN). I do drug screens, but it's because I have alcohol abuse issues. It may be that you won't have to do drug screens. I do have to get forms filled out by my health care providers and will have to by employers. I don't want to give you false hope, but many people are okay with it, especially if it is for mental illness.
I have been very honest and forthcoming about it and people appreciate it. Actually, many people feel for me.
The consequences of not disclosing can be far worse. I don't know if people realize this, but health care providers (i.e. psychiatrists/phyisicians, etc.) are required to report when a health care professional enters in-patient tx or anything like that. It may vary by state. I don't know the severity of yours, but it would be awful to get so bad off and need in-patient help and not be able to get it because you told the Board that you didn't have a mental illness. The consequences could include doing the monitoring program anyway plus discipline, suspension, etc. It's not punishment for mental illness, it's punishment for lying.
I should be getting the okay for work soon. To help me get experience, I want to volunteer (plus volunteering is something I have done for a while.) I would have something to offer then. I started HPMP thread to help other people navigate/know what to expect. It got a little off track in the beginning (with the costs of everything), but it should be good now. I will probably update next when I get any sort of approval for looking for work and what kind of paper work goes with that. Then, I will update on the difficulties of getting work while in it.
I know it doesn't help because I am in VA, not TX...but know that you aren't alone. ((_jackburton))
