Depression is ver common and doesn't take a lot to make the symptoms go away (anxiety is such a common symptom of depression that many meds include medicine that heal both!)
All you have to do is see a Psychiatrist - they will prescribe a medication that you take once a day - and within a few weeks, the depression lifts and the anxiety goes away - it is that simple!
The hard part though, is getting past your feelings of shame, embarrasment or fear of getting to a doctor, but keep in mind - this is what they do all day, everyday.
This is a medical condition and nothing to feel ashamed over - this is no different that having diabetes or high blood pressure. YOU did nothing to cause it - you just have it.
