My monthly cycle makes me so drained of energy to where I have no energy to do anything. If I eat it makes it worse! I just want to do nothing all day and want to sleep, but I cannot do that with work and college. It is disrupting my daily life tasks. I am taking birth control pills too could that be the culprit? So, I was wondering why does my cycle make me like this and is there anything I can do to change this?
