Its hard when newly sober Quack, for me I was drunk for probably 15 plus years, makes you lose your emotions cos every emotion is drunk.
I drank when I was happy, I drank when I was sad, I drank when I was feeling just nothing,.......................
The result is you forget how to be properly happy or sad.
The money bits tough, sounds a hard situation for you.
Don't have any answers, accept help though, don't be tempted to waste what little you do have on drink or drugs.
One thing I do know is that I never regret spending money on my kids, mine are younger but its apparant to me how quickly they grow up.
You get a short time with them so make the most of it.
That said, if my wee one doesn't go to sleep and comes out her room one more time tonight ...................................... aaaaaaaaaaaaagh !
