There is some very good feedback here and I have very little to add for your consumption.
I hope you stick around because there is nothing like this community in the world. Just like life, I have various feelings and thoughts on the whole thing but it is a wonderful place to be and I'm so grateful to have found it and returned.
Whenever I hear there is stress it is often because of people. They don't have to be bad people who use us or abuse us, sometimes its good people who want to spend time with us but by spending time with them, we don't get to enjoy why we joined SL in the first place. I think its important to be open and honest and not be afraid to say no to friends. This might not be the case with you, but I toss it out there anyhow.
