Depression? Doctor myself. please help?

Hello Friend, Good that you are seeking a help here. I can understand your suitation. Accepting  a failure is an emotional fight and it definitely puts your confidence down. However, life is not going to stay the same, you can always come back, if you make mindset change and set your priorities.. Anxiety is the reason for such condition. It's affecting your concentration, memory, lack of interest and also affects few body conditions. You would still need a professional guidance to overcome. There are few lifestyle changes, self therapy, dietary can help you bring back your confidence.When you in trouble, it's always good to ask for help. If you hesitate to meet f2f, why don't go for online counseling. Feel free to reach out to me online through Practo app for further evaluation and recommendation.
