tonstwo, it could be because you have matured. Teenagers tend to think that everyone is watching them and what they say is important. Or maybe if you had low self-esteem as a teenager, now that you have matured, you have become more aware of how little people often notice. But we all do matter, and what we say here is important to you (or anyone here who posts thinks what they say is important to them), and we as "fellow sufferers" will likely understand. Hmm. Does that make sense? Oh, well, I tried.
