Hey mate, chin up. I gotta admit this last year has probably been the worst for motivation and have been very fed up, winter months really didnt help!
You just gotta plough on mate, ive come out other side now and am enjoying it again! As others said get out there and do something, little break away, hobby, surely youve got some v dubs that need modifying
When i was down i wasnt doing anything bar going out to work not enjoying it, coming home and staying in. Its not all that healthy! Go out and see a few mates, and when they tell you they do 40 hours work and take home around £200 a week, thatl make you feel better.
Things aint always as bad as they seem mate, trust me.
