I am able to understand your current situation. U seem to be suffering from secondary insomnia. However more clarity is needed regarding your actual problem, for how long are you on the meds you have mentioned and for what exact problem it was started. I would be more than happy to help you with that. Following some simple sleep hygiene techniques and if needed medical help might be needed for you.
Next Steps
Please have another consultation with your psychiatrist. If needed you can directly consult with me through Practo. Online chat consultation is available.
