If you are having these symptoms, you should really see a psychiatrist as soon as possible. A psychiatrist is qualified to make a diagnosis, and can prescribe medications as well. If you have schizophrenia, the sooner you begin treatment, the better your chances of a normal life.
Medications are crucial; but there are other approaches that can also make a big difference. For this, I recommend you contact the local office National Alliance on Mental Illness [NAMI].
