I think your sponsor sounds great-bringing you round a chocolate cake;
I know what you mean about isolating yourself from the people who could help you when you want a drink-i've done the same.
I think it's my addictive brain like a voice in my head that does that to me it tells me "stop bothering them they've got other things to do than listen to your whining".
Having come back here after briefly relapsing i've been assured that i'm not bothering anyone(these people on SR are really great!!) and now I try to identify and squash the voice as quickly as possible by logging on here-which is of course why i'm here again now.
As for your jeans which are two sizes too small-keep hold of them.
i'm now back into my clothes which were two sizes too small thanks to stopping the booze and i'm now stuffing the big clothes in the trunks that i bought when i was drinking-too big for me now
i did think of throwing them out but i've decided that might be being over confident and anyway it's another reminder for me not to start again;
