I am sorry you haven’t had any replies yet, the forum has been very quiet this week but hopefully I will be able to give you some support.
Your friend is fortunate to have such a caring friend but it is important that you take care of yourself and don’t make yourself sick with worry. Do you have someone to talk to or is there a student counselor or similar you could talk to about your concerns?
Things you can do for your friend are:
Do not give him money or bail him out. This is called ennoblement this is when someone acts as a cushion between the person and the consequences of their addiction so that they do not feel the full consequences of their addiction and the desire to get help wains.
Listen to him and his issues but do not get bogged down by it or ask too many questions, let him get there himself rather than cajole.
Do not accompany him gambling, insttead try and encourage him to do something fun elsewhere, other interests can help them see there is a life away from gambling.
Most importantly take care of you, seeing you seek help for your own issues will be a great example and help you deal with whatever life throws at you.
Keep posting, it might take a little while to get a reply sometimes but there is always someone to listen.
