I do bang on about this at length, but I make no apologies.
The condition called 'depression' is very badly named, because people confuse it with being depressed - which is your current state.
Being depressed is a natural part of the human condition. We have our 'down times' which we use to assimilate the bad things in life - often releasing the pressure with crying which is extremely good for you, and seriously under-rated and supressed in our western 'pull yourself together and don;t feel sorry for yourself' culture. I believe that feeling sorry for yourself and crying at times is not only beneficial, it is essential.
Depression, on the other hand is an entirely different animal. it is a serious psychotic illness, and can occur when the simple 'being depressed' condition mutates into something far deeper and darker, needing therapy and medication for treatment.
The major issue is that because we are not brought up to deal with the former - it can slide easily into the latter, unchecked and unobserved, because we are taught to supress our hurts lest we be seen as (heavens above!) selfish and maudlin.
If you are able to cope with your moods, then fine, but do not fight them because you feel you should. There is no-one at the end of your life with a gold medal for you because you struggled through without help. If you need medication, have it and take it. If you were a diabetic, would you not take insulin in case people thought you were being indulgent? Course not - anti-depressants are emotional insulin, so have a good chat with your GP, and if he recomends a short-term mild dose, have it. You may be surprised how it helps.
Modern AD's are not addictive, and are very successful, so do at least discuss the issue with your GP and be guided by his / her decision.
And you can always chat on here - there are plenty of people with experience who can understand.
