What you might be describing is anxiety. You may be worried about developing psychosis. That, in and of itself, might be what’s causing your “weird head feeling.” There are people who fear developing psychosis. They have health-related anxieties, also known as hypochondria. This may be the case for you.
You might consider having an evaluation by a mental health professional. It might reduce or eliminate your anxiety about developing psychosis. An evaluation is an objective assessment of your symptoms. You didn’t describe any symptoms that would suggest psychosis, but I can’t diagnose you over the internet.
In the past, when you were worried about having diabetes, it seems as though you had an evaluation for that condition. That evaluation determined that you did not have diabetes and you no longer worried about having that condition. Why not take that same approach with your fears about psychosis? It would help you to know the truth and it should ease or eliminate your anxiety and, if you were diagnosed with psychosis, it is easily treated in the early stages.
Finally, the best way to overcome any anxiety disorder, health-related or otherwise, is to always focus on the truth. If you continue to struggle with your fears about developing psychosis, despite there not being any objective evidence to suggest that you have psychosis, counseling could help. Please take care.
