I am in university right now and the lack of energy is the biggest drain on my life. I find that doing all my assignments while I am on campus in between lectures and before going home,gives me weekends off, which I really need after five active days. I found working quite tiring, I was a sales assistant over christmas and the travelling meant my days were quite tiring, so after work I would be wrecked and I'd have to push myself every day leading to a crash on my day off. I was also a till operator which was quite good for me as I could sit down.. lifting boxes and running up and down stairs a lot are just things I cannot do.
I think the biggest struggle was the break times, I find it very difficult to eat and go back to work/class as i need at least a half hour after eating to be comfortable, and sometimes I have had to run to the bathroom to throw up, which is not easy at work/uni. I once had to leave work because I had really intense heartburn, I couldn't even go home, I was in so much pain that I just on the floor in the staffroom, the hardest part was my boss telling me that if I was prone to heartburn I should carry gaviscon with me everywhere, like it was my fault that I couldn't work.
