Hello ThomasP -
I don't think I'm going out on a limb saying the feelings you've expressed are pretty common. The "eggshell" walk is draining! Being fairly new on this site myself, It's probably best at this point to direct you to the many resources available in the "tools" tab and the wealth of information/opinions/suggestions shared by others on the forum.
Most importantly, I want to say "welcome" and let you know you're not alone. Seeking help for yourself on this forum is a great place to start.
