Welcome, if you haven't already check out the P99 newbie guide:

As you've found out, if you're going to die it pays to stay still rather than running around and dying somewhere you can't find again. I make a social button on all my characters for when I'm in trouble:
/yell (just in case a friendly high level is passing by)
/loc (gives me the location co-ordinates so at least I have something to find my corpse again).
