I remember heaps about you lonely. Most of our lives are probably the same as when you were here last. Doesn't stop us caring about you.
You don't have to come here to help anyone. Just be yourself. You are very important and special to so many of us here, even though you may not realize that. We care about you very much. I'm so glad you posted.
On a different note...

Big Bang Theory theme song
edited to add for clarity: I remembered that you liked to watch The Big Bang Theory and I actually started watching it here because of you.
