It might be a good idea to get back with a psychiatrist. The paranoia and hallucinations must be uncomfortable. There are weight neutral meds that you can try.

You could also look into natural treatments, although I really recommend seeing a Pdoc because of the psychosis. I don't know of any natural treatments that treat psychosis.

It's better to try to take care of this now, especially since you have a high pressured job. The stress of the job will just continue to make you unwell and it may not end well for you. I've pushed myself at work too far numerous times and it always ends in hospitalization for me. This last time I took time off and managed to avoid a hospital stay (last February). You need to take care of yourself first.

I hope you find some comfort soon!
