Given you had a low point last Easter in what way did your friend described you as being diffrent by the end of the year?
Is this a kinda pemanat low mood or are there times your like a 'man on a mission' ie working to hard, finding yourslef at the end of your tether cos you can't find anything to enteertain you etc.?
If you are suffering any suicidal ideation or thoughts of self harm I would advice you talk to your GP about it as soon as possible?
If you think these questions are too personal to post a reply to feel free to ignore this post I'm just trying to get a handle on 'where your at' from someione who's had a few problems himself in his time
