Just got on here & saw where you have had such a stressful day. If you could lighten you're load without feeling guilty, I say go for it. Whatever it takes to make you feel less stressed& to not have thoughts to SH.
Hopefully you can keep your 2appointments this week. It's a start, as scary as it is. Don't feel like your ED & past have to be conquered in a week or a year or 5 years. If you feel you have too much to do this week maybe your case worker can at least reschedule your volunteer work from tomorrow to next week. Although I don't know how things work in Canada, seems there a lot of waiting lists...
I'm not good at writing the mushy stuff, wish I was. Just know someone cares & will be here whenever you need a few words to get you thru the night, so to speak.
