Thanks for the support. I'm also happy to see there's another one who has gone through what I have!
I can't imagine me taking on another any time soon but I am putting my knowledge forward to others in the rescue community - and I have learnt A LOT - so i'll be making a difference in some way no matter what =)
That is all that matters. Don't be afraid to get back into it though. You can't be too hard on yourself. At least your heart is in the right place. Your efforts, even ending in failure, are much better than the cats sitting there suffering with no one doing anything. Thanks again!
