All you can do is trying to examine yourself and do what you feel is right. It may be helpful to someone about it.It may be that you feel hopeless in a situation. Try to be realistic; make a list of all the characteristics of the situation and of yourself and then face the facts.
Perhaps you feel weak,not good enough ,ignored or guilty.try to be realistic.It may be true!If it is ture it may not really be so serious.But it may not be true or it may nor be as simple as you think itis.We sometimes only see our own position in a situation.You may be able to change your view of situation by re-defining it,and saying quite simply, "Oh,it could be worse!"or "Well,there is another side to it."Perhaps you have several different problems.Try to see them separately and deal with them one by one.
