Hi Jay,
If there is a possibility that Uni stress has lead you to this point then that sounds like another good reason to talk to the support that will be there.
Whatever the cause of this addiction the important thing is to find a way to stop gambling. Then it’s possible to start to look at/deal with anything else that needs addressing.
One thing I have found though is that whatever the cause there is no “reverse gear”. Once we cross the line into compulsive gambling then there is no return to “normal” socail/recreational gambling.
Find other things to fill your time, other, healthier ways to cope with stress.
Keep posting and let us know how you are moving forward.
