Nice you are taking time out for yourself today. I agree, keeping busy does stop us from becoming to introspective. Living in the moment is a lot healthier.
It's good to hear how helpful the Forum is in preventing you from self-harming. I know a lot about self-destruct, which I liken to self-harm, both originate from the same self-loathing and anger. It sounds like you have a lot to feel positive for; the business, losing 4 stone, pets, great hubby... it does us good to focus on the positives and count our blessings. On those blue days like today, sometimes it helps more to kind of relax into it, if that makes sense. Not putting up a fight by allowing it to pass through freely is a tactic I often deploy.
14 years ago, a stray cat I took in had two little Kittens in my cupboard. Weeks later, I had my very first mental breakdown and I swear those two little kittens pulled me through. Today, they both still bring me comfort and we are growing old together, each with our aching ailments. Then, about 6-7 years ago, someone persuaded me to take on a little JR puppy. Once again, weeks later, I had my second breakdown and he too pulled me through the worst. He still regularly kicks my butt whenever I want to hide away in the flat rather than take him on his 2 hourly jaunt! All three animals mean the world to me, they come first in absolutely everything... and they know it! I never forget that, without them, I wouldn't be here.
