I feel a bit relaxed there when I participate in the same bet with my friends. Because even if I lose there, I get consolation seing from others. At the same time there are some differences of opinion before betting which sometimes creates confusion.
You need to practice gambling without your friends now. It will be hard for you to cope up with future dealing with gambling if you always rely on your friends or if you need to share your experience with them. Not all the times that there are friends around that you can gamble with.
Should be your main goal right now to focus on gambling alone just to have a bit of feeling relaxed too. Sooner or later you will used on gambling alone and not a problem anymore if you don't have your friends around you that available to gambling with you.
