Hi Please visit a counselling psychologist near you. In this situation you need a person on which you trust and share your heart.

Not much of detail mentioned here so that I can give a specific advice. All I can say is that suicide is not worth it. You are getting into such thinking merely because you are unable to control your emotions. I’d really like if your emotions don’t control your life so much as to prompt you to end the very life itself. So. Seek help. Get better. There is a while life out there waiting for you! :)

Feeling low, having crying spells, sleep and appetite disturbances, and difficulty in concentration and attention are some of the signs of Depression. Consult a Psychiatrist for a detailed assessment. It is likely with medication and counseling the symptoms will improve. If you are feeling suicidal or hopeless consult a Psychiatrist immediately.
