welcome to HCM
Best thing is to develop will power and positive attitude towards life.
Forget thebad moments.
Try to involve yourself in activities of your choice, keep yourself engaged
Make good friends who can spend time ans share with you
Go for early morning walk this energies and refreshens you
have a healthy diet
this helps alot to stabilize your your mind.
Try to listen to music of your choice when your mood is off.
Be relaxed and enjoy.
If none of these work out then need to consult the psychiatrist
Hope this will help you
