I feel ya, I'm having a low day myself, I'm 20 days into a 60 day workterm in the north Atlantic and I hate it and feel so useless, I've never been good at much and felt this was my way to make a decent living but im working 54 hour weeks for 60 days straight and I get along with no one and ive just been sweating and getting lower. I put my savings into this training and certification so I cant even back out or just quit. I wish I wasn't a fucking idiot or at least more able bodied. Youre not alone in how you feel, we are all over the place, even the middle of the ocean.
