Am I doomed?
If you are alive and healthy, you are never doomed. There are hundreds, heck more than hundreds of colleges out there and there is more demand than supply - meaning, colleges need kids in many cases more than the kids need college.
So I don’t even need to read your post to know - no, you are not doomed.
Now, you know you have time management skills and perhaps you took on too much. Hopefully you have a coach of some sort that can help you set up some self management processes. Or perhaps your family can help.
So no - you won’t get rejected to every college you apply to - provided you pick your list properly.
And of course it’s worth it to apply to colleges, if you want to go to college.
Get help for your current areas of opportunities so that you can make them strengths.
And then you’ll have a bright future ahead.
Good luck.
