Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. Clinical depression is different and simple disappointment is different. First of all you have to determine whether you have clinical depression or disappointment. For disappointment, simple life style changes should be OK. But for clinical depression, therapy is good. Sometimes you may have to take medicines. To get proper diagnosis, please consult a psychologist / psychiatrist. If you require more of my help in this aspect, Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe the needed psychotherapy techniques which should help you cure your condition further. Hope this answers your query. Available for further clarifications. Good luck.
