It's difficult to diagnose just by this limited information. You need to consult a Psychiatrist and get evaluated again in detail. Your previous psychiatrist was following up on you regularly, so he might have known you & your condition well. But it's not the same with others. You have to discuss in detail about your condition from the beginning along with whatever treatment you have taken till now, dose, course, any side effects etc.
Next Steps
Consult a psychiatrist online and if you are doing well with his treatment, follow up with him regularly.
