I don't suffer from depression but I feel the bolded part is exactly the time that sufferers need to have someone near them, easier said than done but I think it's important for suffers to find solutions to stop isolating themselves, in compulsive gambling it's more often than not when your subconsciously heading down the path of gambling again.
I wouldn't put myself forward as someone depression sufferers should contact but I'm quite happy for those affected by compulsive gambling to PM me anytime, as those that have contacted me previously would attest(please don't do it, it's your business), I'll be as honest as I can about the shit my head throws up,I'll share my knowledge gained through bitter experience and I'll never declare/intimate that anyone has contacted me with a problem/query even inadvertently, your anonymity is yours and yours alone.
