Being between therapists is likely contributing to your anxiety. You also mentioned that your Prozac has “helped a bit.” “A bit” is small. It would suggest that your symptoms are not well controlled. These two factors are likely contributing to your symptoms.
Another consideration is that the symptoms you referred to as paranoia might actually be symptoms of anxiety. People with anxiety disorders tend to fear extreme, irrational and unlikely outcomes. It is fairly common for people with anxiety disorders to believe that they are developing schizophrenia.
Once you begin therapy, you might find that your symptoms dissipate. It is also possible that you need a medication change. Your medication should be helping you more than “a bit.” Once you begin counseling again and have your medication adjusted, your symptoms might improve.
Having two family members with schizophrenia increases your probability of developing schizophrenia but only slightly. There is a strong genetic component to schizophrenia but environmental and psychosocial factors also play a strong role.
You are still very young. At 17, your brain and identity are still in development. The teenage years are a turbulent time. Carefully monitor and record your symptoms and should you decide to see a therapist, sharing this information would be very helpful. Please take care.
