I have had this problem on and off for years now. I am 27 years old and i think i might have an anxiety problem. I have periodic episodes where i feel that a dark cloud has descended on me, that there is no point to anything and i have no interest in anything. This can last for up to two weeks. Eventually the dark cloud lifts, but the feelings are always in the background, almost waiting to show again. Last year i was at university, in another country, away from home. I was OK for the most part, i never really took to the place though. But when i returned to uni after the Christmas break, that's when everything kicked off. The dark cloud, feeling of utter loneliness, of not knowing what to do, feeling of being trapped. I would start crying, unable to stop and i also suffered several panic attacks. I decided to leave that uni and return home. Now i am a few days away from starting another course at a college much closer to home and am again experiencing the same problems. One minute im ok and i'm gona go for the course, the next tension and fear build inside me and all i want to do is run away and have nothing to do with the course. Am i going mad, because i feel like i am!!!
