Losingit,
I went through an awful, awful time once. It lasted for a few years. Very emotionally traumatic. I'm quite amazed I survived it. At times, all I could do is to remind myself "just breathe." Some days, putting one foot in front of the other seemed near impossible. So..."Just breathe" worked -- I focused on that.
Also, when things would get quite difficult, I would have a cup of tea. It may not have made anything any better but the way I look at it, it couldn't hurt any.
If you find yourself teetering, perhaps have that cup of tea. It may not make anything better, but at least you will have had a cup of tea.
