Krystal, How Old are you? I'm sorry to say but for a "Psychologist"(Am i getting that right?) You're acting incredibly Childish.
Your sig is just proof of this. When confronted with a opposition you resort to "FINE LOL I DONT CARE I DO WHAT I WANT" type of attitude? Even i stopped that when i was 12. The best solution to a problem is to correct those who are misinformed about it.
If you want people to stop thinking You're a troll, Don't give them a reason too. When making a thread address a point in a coherent manner. Never post while angry cause it'll look bad. Trust me when i say if you post angry your thoughts never come out right :\.
Look at Hordecore, Eventually everyone began calling him out of being a horrendous troll, But He's stopped making threads now and started actually responding in them, mostly coherently. I still think he's probably a troll from FFXIAH, but at the same time He's trying to break the Stigma.
You should start by removing the childish sig, And attempting to act like You're not a troll. If your intent was truly never to troll, Eventually people will understand and see that. Then you should continue by not making so many threads that only complain or invite negativity.
Becoming the very thing you are being accused of is never the right answer, any "Psychologist" should know this.
