I turned sixteen years old about four weeks ago and I have been acting really strangely since then. I feel unhappy most of the time apart from random periods where I feel kind of hyper/over the top happy. I also seem to be losing my temper all the time over the smallest of things (and actually it has been like that for a while now) and getting so frustrated that I almost break down into tears, although nobody has noticed as I don t like crying in front of people. Even on my actual birthday when I should have been genuinely happy I just felt like I was faking it and felt oddly distant from what was going on. I really just wanted to be in my room and alone. I have also put on a bit of weight which is kind of good since I was diagnosed with Diabetes Type 1 in January and I was under six stones at height of five foot but now it is getting slightly too much - I have got a bit of a belly now and my Mum commented on it. I decided to ask this now since I haven t been sleeping well and I have been more irritable, not able to laugh even at stuff I would have found funny before as well as unable to concentrate on revising for my exams and I keep thinking about what would have happened if I died after my diagnosis instead, as I did come very close to death, and what would be the reaction of those I left behind. What is going on with me since I am usually quite a happy person and my friends have commented on me being much sadder and not keen on going out, will it go away?
