Samantha I'm sorry love but that's b(llocks. Depression is a REAL thing. It isn't made up and it certainly isn't something that you can "just get over." Would you say the same for a diabetic who needed insulin or me who needs to take a cocktail of drugs every day to be able to keep moving?
Yes it's true that you might have to try a couple of different ones to find the one which suits you better, but I really don't think it's something you should dismiss - especially if you are as low as you sound atm...
