Hello sir, I am 17 and I am bit confused. I become anxious very fast and for very little things. I used to think what if this happen or what if that happen and once a possible bad outcome come in my mind, My mind blows and from that moment, I couldn't concentrate on anything and I started to feel as that would certainly happen. This is happening from small to big things over 4 months. Moreover when I did any work or someone told me anything important, I become anxious about what if the person had told me something else and I misheared it, this happens every time. Sometimes when I went to bus stop to my school and saw noon, I started what if there is holiday and I reached it. There are millions of scenario like that. I double confirm everything. I am tired of doing it. The case hasn't been resolved yet, whenever I try to study my mind always swings, it become happy sometimes and sometimes very sad and this doesn't also let me study. And the worst thing is that I can't stop thinking whenever I do it, it pains my head. Tell me what I am suffering from? How do I get rid of it? Please don't tell me any medicine.
