I'm not a doctor and so if both your therapist and psychiatrist are saying you will not become schizophrenic, then I have to defer to them. They are the experts. Now what you need to work on is getting rid of doubt.
How do I get over this doubt? I'm seeing my therapist once a week right now, and I'm limited what I can take medication wise, I'm nursing so I can't take anything to help with panic attacks. I just feel like I'm going in circles!
You are hopefully learning cognitive beahvioral therapy. Replacing negative thoughts with positive ones, controlled breathing when you panic, journaling. There is a great book called Self-Coaching by Joseph Luciani which I found to be really helpful.
Thank you JGF for the book info I believe this will help me.
