With whatever little you wrote, you seem to have challenges handling your emotions, therefore you are dealing with situations emotionally.  Talk to matured people and/or parents if you feel comfortable. You might feel better.  However if you feel that they would snub you probably consulting  a Counsellor will help. Not worth living with such problems. Resolve and move on in life. 

Loss of interest, decreased concentration and attention, feeling low and disturbed sleep or appetite are some of the signs of depression. Consult a psychiatrist who will assess you in detail. If you are feeling suicidal or hopeless, seek professional help immediately.
