I understand your concern. The way to find out if you have adhd or not is to undergo a detailed evaluation with a nearby psychiatrist. However inattention only over the last 2 years (and not since childhood) may be due to depression / anxiety or drug abuse as well. More clarity is needed regarding your problem. However it is easily manageable with appropriate medications and some therapy, so that dysfunction can be reduced and your quality of life will improve. I would be more than happy to help you with that if you are looking for further online assistance. You can directly consult with me through Practo as needed. Online chat consultation is available.
