For a while now I have been feeling constantly tired and often cannot be bothered to do anything. I always want to sleep and find it difficult to get up in the morning. I also have gone from being very ambitious and self confident to having low self esteem and giving up on things that used to be important to me. I've even started tripping over words but its not exactly a stutter. I am more irritable and snap at people which is unusual as I always used to be very in control of my emotions. Sometimes I get urges to just start crying for no reason and I get suddenly tense and anxious about small things before realising nothings wrong. My general low mood comes and goes, sometimes I forget about it for a while but then it comes back. Its sometimes worse than other times, at worst it makes me want to be by myself completely and think, cry or sleep. I think this all started to happen about September/October last year but got gradually worse. It almost went away for a couple of weeks recently but in the past week its coming back. I'm not sure whether I'm just stressed and making a fuss about nothing or whether this is something to worry about. It isn't constant so im half convinced i'm just being silly and overreacting.
