Warning: Keep knife out of children

Also - for the stuff you're not able to talk about with others, one possible thing is to talk about it to yourself. Open up Notepad and write the LJ post you would if you were able to share these things, then look back over it, re-read it, edit it, whatever your process is for using written words to help you understand and deal with things. When you're done, you can save it, post it to LJ privately, delete it, whatever you like.
