What do you think..is it really depression?

Kasia

My boyfriend broke up our relationship not that long ago, after two years of being together, by saying that his feeling faded away and that he needs some freedom. Since then all I'm doing is constantly crying. I don't have any appetite and if I eat once a day is good. Sleep is gone as well, I'm sleeping for like 3 hours daily, struggling to fall asleep and constantly waking up! I even started to self harm because it's so difficult and painful! I still really love him! Few people thought it might be getting to the stage of depression and said would be better for me to see a doctor. But I really don't want to go. If I go I'll only burst out in tears without being able to say anything! What should I do? Do you really think it could get to the stage of depression? Help please..!
