When I was in hospital the second time around, I asked a man with bipolar how he knew he was unwell/ delusional/manic/psychotic. He said he knows by how much the delusional thoughts are bothering him. I gather he was obsessed by his particular delusion which he shared with me and I cannot share it here with you here as I dont have his consent. I can say it was a scary and worrying and an unpleasant delusion and it was having a big impact on him because he was thinking about it all the time. I don't know if this helps but I have since found this helpful.
Generally I believe that asking questions is a healthy strategy that can empower you to understand your own illness and take part in your own mental health treatment. By being honest and having a good relationship with your treating team you are helping them know how they can best help you and what your worries and fears are and the impact they have on you.
It also helps the psychiatrist understand the problem and to get the diagnosis correct and thereby give you the correct medication/treatment. Is there a problem causing you to have trouble telling your psychiatrist but that you are ok to tell your psychologist instead? With complex mental ill health it is helpful if all the team know what is happening. Is it possible for you to talk to your psychologist first and tell them what's wrong and then maybe they could talk to the psychiatrist for you about what is happening, because if they are also worried by the symptoms you are having then it is reassurance that talking to the psychiatrist is the right thing.
