It sounds like you're going through a difficult patch alright and your question suggests you probably have a pretty good insight into your own situation. Yes, you sound stressed and yes your mood sounds low. You seem frustrated and some things aren't working out as you might have hoped. In this regard you're actually responding in an entirely predictable fashion. You are taking exams within a competitive environment and your perspectives are probably distorted (hardly surprisingly) as a result. It sounds like you are well aware of the stock answers to questions like yours so I won't suggest ideas you may find patronising. I would suggest that your emotional reaction to your circumstances isn't helped by feeling you haven't anyone to turn to, but this is more important to some people than others. Very often strong negative emotions can leave people feeling they are losing it in some fashion. Mostly, they pass, and we learn something along the way. You are the best judge of your situation and if you feel you need help I would recommend a visit to your GP. They may suggest support alternatives based on what is available in your area. Try to keep your life on track. Get fresh air, sleep properly, stay away from cigs or drugs or alcohol, and attend to your diet. If you ignore these things your body will react as if it is stressed and this will make you feel worse. Feel free to write back. I know I haven't covered all eventualities but we do like to support or just listen where we can.
