Chap,
What I see is that, firstly, you are missing confidence. You can do many things and do better. Just forget all what happend and now on, make yourself busy. Secondly, you are missing friend, you cannot live without friends. Go out and find some friend can talk. You will be happy.
小心!Not trying to scare you. You must keep yourself busy. 知道gambling最可怕的是什么吗?not a one-shot loss, no matter how much, but“反复”,absolutely like taking drugs.我有切身体会。You good luck! Give all cards to your wife for safeguarding. You might be able to quit it cold turkey.
