Still not getting my act together since I got back from Palestine. I can't be bothered to plan, to buy healthy food; I'm eating carbs - huge great choc chip cookies - like there's no tomorrow. I still manage my daily walk but that's about it.
I know it's the dreaded black dog of depression but here's the weird thing - in past years, I've just succumbed to feeling dreadful until it lifts. This year, having a better understanding of being able to say 'oh, it's my seasonal depression', it actually makes me not try to do anything to lift it; 'it's just my depression'.
I'm doing the minimum required to not fail at my job.
I'm stressed to death about managing my old dogs' declining days.
I crave company and long for solitude.
I'm eating like a garbage disposal.
I'll try harder today.

Rosinante - somewhere amongst the depression, you should be able to see that keeping away from what you know is good and positive is having the negative effect that you didn't want. I am also seasonally affected, and have trouble some days too. There are so many things to be thankful for, many of your own making. Try to find some positives in every day. If I were you I'd write down each positive you get from each day. This might help
Also with respect to your beloved four legged friend, remember you have had a great life with him/her, and you have both been enriched by being together. I know it's hard. I know you feel down, but you deserve to continue the way you started. You owe it to yourself to finish it.
