Yes indeed. Weed / Alcohol are nervous system depressants with the ability to cause all sorts of problems including depression, anxiety, psychosis or even dementia. However it is manageable with appropriate treatment. Some therapy sessions along with medical help might be useful for you. I suggest you visit a nearby psychiatrist for a detailed evaluation.
