Hey there! Maybe I am the only one who thinks that missionary work is tough sometimes and it can make you struggle. But I do not think so. Missionary work is pretty tough often. Especially if you take it really seriously and try too much or push yourself too much to be a better sister/elder. I know now that I did have a predisposition to get mentally exhausted when I have too much stress. On my mission I managed to sleep only four hours a night. That is way too little for me at least. Put stress of missionary work, challenges with your companion(s) and trying too hard and too much on top of that and you have yourself a situation similar to what I experienced. When I came to the hospital after my mini mission they told me my diagnosis: psychosis and also my progress (like development of the mind as you grow up) was "locked". I sometimes joke that I am really a 20-year old in my mind. I do not really know but I did not become an adult when I was 18... more like 38 :D Of course...
