When you join a gym, it takes consistent efforts and time to get your body in a physically fit condition and after that you still have to continue to maintain the fitness. And people spend a lot of money as well to achieve this goal. The same holds true for mental health and mental fitness. Therapy takes time and consistency on your part as well as the therapist’s. So you will have to continue therapy along with medication. Anxiety and depression keep getting worse over a period of time and as you are young right now, it may take lesser time than usual. Be mentally prepared to give therapy a few months. But the end result is your mental health and that is what should matter. Do not self diagnose or self medicate. It’s never the right solution.
