Hi Lemarr!
I'm new today too!
I know what you mean about seeing everyone else "happy" and feeling kind of left out and dejected. It's like watching life from the sidelines... but, it's important to remember that just because we aren't doing what everyone else is doing, we aren't "less" than they are. We just like different things! And I, like you, would rather be alone and at home. If that's what you're comfortable with, it doesn't matter what other people are doing!
You said that you like to escape into created worlds... me too! Do you write stories or just go your "happy place"? I find that my created realities are much more pleasant than the "real world".
I like music too: classic rock being one of my favorites!
