I would suggest you to share your problem with a good psychologist rather than making your body pills dependent. Also if I could help, i can suggest you to divert your mind elsewhere. I know its not that easy but still avoid thinking about what your stressed of. Try meditation, watch movie and the best thing is to talk to someone. They may be your family or friend.

I am able to understand your situation. You seem to be suffering from insomnia maybe due to depression. However more clarity is needed regarding your actual problem. I would be more than happy to help you with that. It is easily manageable. Following some simple sleep hygiene techniques and if needed medical help might be useful for you. You can directly consult with me through Practo. Online chat consultation is available.
