Thank you so much for replying, WePow and elliemay. I feel so grateful I could cry.

I will reply properly later but right now I'm going to build on the success of having made myself a soothing breakfast and go to a craft store to look at all the beautiful things there and maybe get a few things to make a 'things to look forward to in 2011 project', so that whatever happens with my partner, there will be other good things in my life. Baby steps for others, but just getting out of bed at the moment is a giant step for me. Thank God for DBT. I wouldn't have been able to do any of this without the skills it taught me.
