Perhaps you should try counseling. I feel a lot of what you feel, a lot of the time. Counseling helps, because you're talking to a person who is neutral, and can see things from outside. Sometimes we're so close we can't see the forest for the trees. We feel like we're in a rut we can't get out of, and feel as if there are no possibilities open to us, and we get even more depressed. It feeds on itself, and things get worse because we can't see a way to climb out of it on our own.
You also mentioned feeling depressed. I have a problem with depression myself, and I've found that Zoloft helps to level me out well. If you have clinical depression, getting something to help with that first may help you feel better and consequently to see a way through things more clearly, without the cloud of depression coloring your views.
When you're depressed, everything sucks. You're so busy feeling miserable, that you can't see the good in anything because it seems like EVERYTHING'S going wrong, and usually all at once. If you see a counselor and find that you ARE clinically depressed, you may be able to get medication for it. Once you level out, and are more able to feel okay about things, and not automatically see the bad side, it may be easier to address everything else. Without the influence of the depression, things often seem more hopeful.
Good luck to you.
