I understand your concern. However more clarity is needed regarding your problem to decide on the severity of your condition. Weed / drugs affect the nervous system which have the ability to cause all sorts of problems including depression, anxiety, psychosis or even dementia. However it is easily manageable with appropriate treatment. Some counselling sessions along with medical help might be useful for you. I suggest you discuss with a nearby psychiatrist about your issues. I would also be more than happy to help you with that if you are looking for further online assistance. Discussions will be held confidential. You can directly consult with me through Practo as needed. Online chat consultation is available.
