Well what can i do for stress or anxiety because it becoming a promblem causing physical and mental problems but i get test and everything's normal?

Family practice : Sometimes anxiety and depression is a result of something subconsciously. Even with normal exam and testing there could be a hormonal imbalance. I would recommend seeing your dr again and get treated and get counseling.

Stay active: Exercise is a great way to relieve stress. Your body releases endorphins during exercise, which can help you feel calm. If you exercise 30 - 60 minutes a day, your stress levels can improve. When stressed, take 5 slow, deep breaths with your eyes closed, then roll your shoulders forward 5 times, then back 5 times. This will slow your heart rate and release tension in your neck and shoulders.
