Procastination

What can I do to stop procrastinating so much? Whether it's for school, classes I'm taking outside of school, working out, or literally anything else, I can’t stop pushing it off. I will spend most of a break or weekend doing nothing because i can’t get myself to be productive even though i have so much to do. When I know it's difficult or a lot of work or time-consuming, or when I'm not interested in doing it, it becomes so hard to complete the task. And then I get anxious from not doing it because I have to at some point and it's worse every day I push it off. This is the reason I usually don’t do as well on projects as i do on tests, because its so hard for me to put time and effort and work into it when I'm not being forced to. It's worse when there's no clear deadline too. My life is literally falling apart rn because I'm waiting until the last possible moment to get these things done and give myself so much stress over not doing it.
