I hear you. I get the same way, often in waves. I find that once you get a grasp on a goal or feel that more hopeful state of mind, you have to hold onto it with all your might. Don't let it slip away. When you feel that sort of pull to get up and do something, you have to get serious and do it! Remember who's in control. Don't play the victim and don't get down on yourself. It's all up to you to be what you want and hold your head up above water.
Doing something active like going for a run or lifting weights in your room-- whatever, it gets your endorphines pumping which makes it all the more easier to stay motivated. Honestly, as hard as it can be to get yourself moving, it triggers a chemical reaction in your brain and your body and it'll stay elevated for the rest of the day.
The trick is to not put so much pressure on yourself. You don't have to be super confident overnight. And skipping steps never works which is why you find yourself right back where you started. Learn what ways work for you to cope first and that'll get your confidence back up. Just trust yourself! You can get there.
