I don’t know what’s wrong. I live with just one flatmate and recently she got a boyfriend. Today she was at work and I was all alone in the flat feeling down and lonely too but not too bad. Both her and her boyfriend come in later in the evening and we all end up chatting and then somehow I just get this random burst of energy and I really want to do something - we jokingly talk about going to Bingo or to the cinema or bowling (at 10pm) until we all decide to drive to the beach for a walk. I don’t know why but I was just feeling really quite ecstatic at that moment and when suggesting all those things like my brain thought yep I can do all these things but in reality if we actually went somewhere I wouldn’t want to and I’d rather stay at home. So we all went and I was still feeling good until we got there then all of a sudden I just felt low and empty and I was a bit of a downer for the rest of the time. It was like a switch went off. We weren’t out for long but literally the second we got there all the positive and excited feelings just vanished and I felt so awful and as soon as we got back I went straight to bed on the verge of crying. What’s wrong with me? I wanted to have fun with my friend (and her boyfriend) but the second we started doing something I really didn’t want to. This happens a lot too like I make plans, get really excited then immediately want to stop as soon as they start.
