I've been really struggling this term, well, all terms, but this one is the worst yet. I'm in three online classes, have a spinal cord injury, bipolar and some type of panic disorder. My stupid psychiatrist flat out refuses to prescribe any medication whatsoever, she said (and tell me how absolutely backwards this is) "Once you can show stability for a few months, I'll consider it." ??? really? I'm kinda under the impression that a huge part of why I'm losing it is that I"m NOT on meds for my bipolar. I am on the verge of dropping out of school, literally 2 weeks before my "graduation" (tho the financial aid department lied to me when they said that my tuition was fully covered by loans and until I pay off this out-of-the-blue $1000+ balance, I can't graduate or get transcripts).
But- to touch on the anxiety/procrastination thing. I think it's normal for them to go hand in hand. What happens when something makes us anxious- we avoid it, which when that something is homework, becomes procrastination. I've been terrible with it this term, being so anxious that I am spinning and just can't even think about school, let alone actually do anything with it. The perfectionism doesn't help either, but that's a double edge sword- it's what gets me A's when I am able to do the work.
Good luck, hang in there, and all the other useless cliche's I know they don't help me, but always say them anyway, lol
