(your chart with transits and progressions)
As waybread said I don't see anything terrible but I wanted to go with progressions to see if there was anything going on with your chart right now that's making you feel down. There are a couple things which stand out - one is transit Chiron having recently crossed your descendant into your 7th house - this would have coincided with getting hurt by others somehow (typically) or getting some undeservedly painful evaluation. Chiron itself passing through H7 speaks of thinking of the ways you have been hurt through relating with others. The other theme related to this one is that Neptune is in conjunction with natal Venus (you have it in the same degree as me basically) and usually you end up with some disillusionment around this transit such as being seriously let down by someone who turns out to be not what you believed them to be. In either case we are talking about being mistreated by others rather than anything being wrong with your chart.
There are a couple of aspects in the natal chart that could give you trouble, though. Between '87 and '90 Saturn and Uranus were in conjunction in Sag-Cap (decans 3 and 1 of those respective signs) and they could cause problems if they would get entangled with a pair of personal planets in opposition say in the natal chart. You have such an opposition between moon and Venus (and Mercury) and all those planets hit Saturn-Uranus by square.
Saturn's effect is the more problematic one for you since it's the closer in orb to Moon-Venus while Uranus picks up the square to Mercury - this is kind of a good thing since Saturn is easier to deal with than Uranus but it can still make life tough. Moon-Saturn basically can make you feel like it's not ok to feel certain things or to "bother" other people with whatever you are feeling (Saturn always seems to want to make you figure it out on your own) while Venus-Saturn can be discouraging for relationship since it feels like it takes too much work to make one work or somehow there are too many duties and responsibilities involved. Because these are both feeling planets these aspects can give you this underlying feeling that things are just too hard and unpleasant but they need not be, it is that natal Saturn that is making it seem so. The flip side is that if you can get Saturn relatively happy (by for example having security and structure in your life) it can allow Moon and Venus more freedom to try to do their thing and seem to run your life a bit less.
