I can understand your dilemma and the pros and cons list is helpful. I know there is value sometimes in stepping away and "regrouping" or grounding yourself again before getting back into the mix of things to be refreshed to retackle the school environment. School is not going anywhere it will be there. On the other hand, it can be hard to be away but know it is there and you want to get it done but at what cost. The list is very logical. How are you feeling? Do you need/want some time that it might put you in a better position/state when you go back if you took just a semester away or not really feeling it? What are they seeing that you are discounting? I know there are times when others close to me do see/hear things from me that I do not pay attention to myself. I have to really look at this. In the end, I have to go with logic plus my gut. School will be there no matter what you decide; your health is what is most important whether it be to continue, or to take a break and regroup. do whatever you have to to take good care of yourself.
