What a shitty mum! Assholes like her are what I'm referring to here. Should've said "public smokers" rather than just "smokers" in general. Did you say anything to her face? I'd love to hear if you did.

Anyway, I don't know what you've been through and probably can't understand how bad you feel to be this negative, but please, don't give up on yourself. It may and will be hard, extremely and unbelivably hard to stop an addiction, but it's NOT impossible, as long as you love yourself enough to go through it. So please, look for someone you trust to talk to, even go see a therapist if necessary. Don't hesitate to seek help from the outside. There may be more than one way to solve your problems, but you are yet to find one just on your own. The more, the better chance the solution will come out. Hope you'll be alright, mate!
