Embarrassing

So today I went to my judo class . I usually arrive early to class and help setting up the mats . It’s been a week since I’ve started learning judo and it made me realised how slow and inflexible I am. Last night I had been up whole night because of my college assignments and some mental frustration and breakdown . And I woke up late . I just had lunch and just had some milk before going to the judo gym. After some warmups and drills I was feeling dizzy and fainted . My sensei helped me and made me feel better . And now after back from the gym I feel bad and embarrassed because it made me look how weak and stupid I am not the mention I kind of embarrassed myself in front of other students, the kids .
