It sounds like there is too much on your plate. Which is to be said of so many of us here - we are masters of overwhelming ourselves, aren't we? Seroquel that you take is for sleep only, it is too low to act as an antipsychotic, so you have no protection against suspicious thoughts. I think you need to talk with the p-doc right away, who would probably up the Seroquel or invent something else to match the difficulty of the presentation. I know that going off Lithium as you become older is very difficult. I once was on a psych unit with a lovely 70-y-o woman who also was taken off Lithium (I do not know why). Poor thing was in and out of the hospital because nothing could substitute for Lithium which she had been taken for 40 years before and been stable on.
