Is it normal to become depressed?
So... I've had depression when I was a little kid (early elementary school) and had been suicidal because of it. For the most part, I've gotten over it and have been enjoying life fairly often and usually pretty happy. But... I hate the perverted side of me and whenever it gets a little out of hand, I immediately start to regret it and I almost instantly go into a near-depressed state where nothing really matters anymore (save only a handful of things) and I don't really want to do anything, including eating, drinking water or any other fluids (not an alcoholic), going to the bathroom, etc. I'm usually like this for a couple days or afterwards. I basically just end up sleeping.
This has caused some issues with my girlfriend, who knows full well that this does happen (she's had to put up with me like this a couple times before this past year), and she gets a little upset because of it, especially when she's in the mood... This mostly happens when I start to ask her for something and she says that I'm starting to creep her out...
So... I'm wondering if this is normal or not...
P.S. I don't have any insurance or the money to get professional help, so don't even suggest it... because if I did, I'd have gone to them already for a couple issues I have...
