The symptoms you reported (low confidence/ low self-esteem, feeling miserable, feeling that you have no energy, loss of appetite), as well as the previous history of self-harm and two attempts of committing suicide might indicate that you are experiencing depression.


Depression is a mood disorder characterized with low moods and an aversion to activity. There are several types of depression, including: major depressive disorder, dysthymia, bipolar disorder, and cyclothymia. All of these disorders need a longer period of observation by a psychiatrist in order to be diagnosed properly.


The treatment would be decided depending upon the type of disorder. Perhaps the most difficult part would be to admit that you have depression and to take the medications as recommended.


In the end, please consider that the teenage period is hard for many. It is a period when you try to reach a certain image that the society expects from you. It might put more pressure than a young person can cope with. If no depression disorder is diagnosed, then you might want to visit a psychotherapist to help you with the low self-esteem and to improve your social skills.
