Low points do kick in. I’ve not gambled for 8 years or so and I still get low at times. What helps is remembering that I’ve been there before and that these feelings pass. What also helps doing things that will lift your spirits – whatever that is for you. For me it is music and certain comedies – but we are all different.
No friends must be difficult for you and I would suggest that you look for ways to make some contact. As gamblers we are not good at friends because we feel shame at what we do. When I was gambling, I would not let anyone come to my place because of the mess it was in due to a) all my money going into slots and b) spending so much time gambling and earning the money to gamble that there was no time for housework.
I made friends slowly through taking courses so that I met the same group of people every week. Do something that would really interest you – it needn’t cost a lot and might even be free in some cases. Also consider voluntary work?
Thank you for posting and I wish you well.
