When I have projects like this all piled up, I try to tackle one thing at a time. I set goals around time, and if I meet that goal, I can do 5 minutes of my special thing. So I aim to have things done fast, and usually I get them done faster than I think I can, so all is better. Just take a deep breath, tell yourself you CAN do this, which you definitely can, and go for it. Pick one project that isn't as big and start with that. Then do a bigger one. Alternate back and forth between big projects and small projects. Make check-lists, rather than schedules. (Say "I'm going to take 10 minutes to finish this step" and then do that step, rather than setting times for each step before you begin the project, set the schedule as you go. Make a goal to finish a bunch of stuff before you go to sleep, but don't add it all up and pre-schedule it, because that will make you more stresesd.) I like index cards with checklists to keep track of things, but that's just my way of doing things. Don't over-schedule yourself, like I know you really want to do for the structure. Make lists then schedule as you go. You can do it!!
