Mugz, you need to snap out of this mate, it's really not good, I know how tempting it is when you're depressed to smash the drink and drugs, I know about all the thought processes and the self-loathing and everything, but you need to grab the bull by the horns here, reassert control over your life. There's only so much anyone else can do, you can lead a horse to water but you can't make him drink. I'm trying to find another livestock-centric cliche, but I'm drawing a blank, so I'll leave it there.
Cane, once you get into cycling, you can't believe you ever walked anywhere. I've been squatting my mates' living room, and even though the pub is a 5 minute walk away, I feel like a total dickhead walking in the cold and the dark and the rain while they zip away. Honestly mate, change your life, and you end up with gigantic powerful thighs to boot.
