Extremely stressed and can’t keep up

First off let me just say that I had no one to ask about flex terms and the difficulty of them; taking 5 classes this semester, 3 in flex and 2 normal paced classes. I have something due every day, online schooling sucks, I teach myself everything and professors are no help. No late work is accepted at all, I’ve been doing good on that but only because I’ll stay awake 24 hours or just sleep 5 hours. This is my first year going back to school after having a break for 3 years so I feel like I came back dumb. Luckily I am doing good or B+ on all my classes, its just I am exhausted and am constantly drinking coffee or Red Bull everyday (which I hated both before this!). I know people do college and work or college and a baby, but I had to quit my full time job in order to keep up with the constant due dates every day. I feel so dumb taking harder classes together (anatomy and physiology, math, chemistry, psychology, and English). Today I have a A&P chapter homework and a test due before 12 and it’s 6pm, I have to get started on an rough draft for my essay and turn it in for english also and I’m only 25 pages in the A&P chapter since I need 10 left to take notes on. I have to read 15 chapters from 2/28-3/10 because I’m a week behind in psych (that one is at your own pace as long as you finish by 3/10 all assignments) BECAUSE OF THE OUTAGE IN TEXAS. I don’t have time to be with my bf and he doesn’t understand sometimes because he says he misses me, I just needed to vent because I don’t want to drop any classes as I’ll feel like a failure. For my second semester, I will definitely do all regularly paced courses.
