Some of the symptoms you have described seem to be indicative of obsessive compulsive disorder. Please visit a psychiatrist so you can get a thorough evaluation. There are effective medication for these symptoms. Usually a combination of medication, therapy ( CBT and other techniques) and exercise works best to relieve the symptoms

I understand your distressful situation. You seem to be suffering from significant OCD symptoms. However more clarity is needed regarding your problem to decide on the severity of your condition. Don't worry it is not your fault, it is the hormonal and chemical fluctuations in your brain which is taking a toll on your mental health. It is easily manageable with appropriate treatment, so that dysfunction due to the same can be reduced and your quality of life will improve. Some therapy sessions along with medical help might be useful for you. My clinic is at OMR chennai. I would also be more than happy to help you with that if you are looking for online assistance. Discussions will be held confidential. You can directly consult with me through Practo as needed. Online chat consultation is also available.
