Well done on being honest with your mum FishFace.
I would advise against looking at race cards and/or giving tips to your friends. If you do that then sooner or later you might have a lucky streak which will really kick the urges back into life.
Do your friends know that you have decided to stop gambling? You don’t have to tell them about any problem but “I’m not interested anymore” soon brings and end to any conversation about gambling.
