Wow you are so brave ! Way to go!
So what types of self care do you already do?
Can you set up rewards for your self each day?
Do you CBT or DBT?
Can you be your own best Yfriend? Can you cheer your self along each day?
Presuming you work at a desk, could you leave a memento on your desk to greet you in the morning?
You could set up a origami or suchlike in your home as a treat or reward at the end of the day so you have a self soothing activity at the end of the day to look forward to.
Random acts of kindness are also a good way to stay connected to people. I got a stack of them into today. It is most rewarding. My energy was positive and I got some lovely reactions and a couple of times people went out of their way for me too. At the coffee shop the woman said they were closed but that she could make me a tea. So she opened the cash register so I could pay and then when she said now the bookstore doesn't close for another half an hour so you can take your time to enjoy your tea, which was rather lovely.
Catching people doing good things and acknowledging that is a good way to go.So writing an email of appreciation at the beginning of each and end of each day or even a verbal compliment could be good as well.
The happiness challenge by Shawn Archer has a great system for building gratitude and positivity. Maybe you can do it on your own. Maybe one day you can introduce to your work place one day.
Maybe you can get someone to sms something like "Stay the Course, you can do it." On the hour for the first couple of days.
Send yourself some flowers and sign them Anonymous. So the talk the first day is of excitement and curiosity.
Perhaps organize a massage for your self at the end off the day.
I have no idea of what type of work that you do, but I hope these ideas can spark off some creative problem solving of your own.
Good luck. Be Kind to Your Self. And Report Back it is always nice to know how people get through!
