It sounds a bit like schizoaffective / Bi Polar type , the doctor seems to think i have it , some of my symtoms are simmilar to what you mentioned so i wouldn't be surprised , best just asking your doctor to see what he / she think's.
The main thing is you can't be both and I will be glad when they get their heads out of their a$$es and give you a diagnoses so you can start to work on this with the knowledge you can gain by seeing where you fit in. I am type 1 bipolar. I hear and see thing sometimes but only if I stay up for weeks. I would start keeping track of your moods and sleep patterns so that when you go to the doctor you can be prepared for him/her even if they are not prepared for you.
There are many types of bipolar and some do not experience hallucinations or hear voices. Look at the DSM VI sometimes which is something your doctors should have knowledge from anyway. It may help. The main reason to know whether you are schizoaffective or bipolar with psychosis is the treatment is slightly different. To the best of my knowledge those with type to with hypomania do not go through hallucinations or hear voices, but I cannot be boderline personaltiy disorder, bipolar, BPD, schizophrenia, you are either one or the other, not two of the same time. You scan have symptoms of a couple of them. You can also have different some other disorders on top of ONE of those like ADD, ADHD, OCD, Hypochondriac, bulimia, and many others. I have gotten this information from a very good psychiatrist. I may not be corredt on everything but I am correct on alot of it. look into it for yourself, don't try to diagnose yourself, but do voice to your doctor and if he/she can't figure it out, go and get a second opinion.
