FRAF username regrets

When i signed up I used my pesterchum handle. It's not the greatest as it does not follow the GCAT formula but I could always make a new one later. Only now did I realize i could have claimed emijones or emi or gamzeefreak (which is how i go by on twitter). I have had a long history of being in turmoil simply from my username, biggest example being on neopets where I have had abandoned multiple accounts simply due to the fact that i didn't like my username but was unable to change it. Does anyone else feel the same or am I just crazy?
