Hi, Rahul. I am sad to hear you are still feeling suicidal. But please remember this. Suicide is a permanent solution to a TEMPORARY problem. It also leaves UNBEARABLE wounds to family members. There are a lot more good reasons why people should not commit suicide.
As for ur issues, can you try to go out to movies, or play ur favorite sports or any other outdoor activities? If you can't find friends to play with u, even hang out with ur cousins or neighbors ur age or ur brother. Remember you are barely 19, with so much future ahead. I have a confidence in you that you will rise above this and become a happy, successful person in the future. Take care.
