I have put some self-help tools in a blog post - feel free to peruse - http://empathcommunity.eliselebeau.com/profiles/blogs/my-empath-experiences-and-empath-tools-for-healing
If you have any question after reading it, feel free to ask, here, or pm. In my experience it can be a tough journey, even with good tools, but with good tools it should become mostly bearable and one gets good days too again (even some great ones )
