This really ticks me off. I’m going into my sophomore year of high school next school year. In the 7th grade, my history teacher thought I was mentally ill. In the 8th grade, my wrestling coach and another wrestler thought I was mentally ill. In the 7th grade, I tried for the football team and they were dicks to me but then later in the day started being all nice, which makes me believe someone probably said something like, “he’s retarded, leave him alone.” I also suspect my mom of thinking I’m slow or mentally retarded due to the way she acts towards me. She has normal conversation with everyone else, but when she talks to me she talks to me in that little pitch you would use when talking to a toddler.

I also suspect my dad, step mom and step sister of thinking I’m retarded for the simple fact that when they’re talking next to me, they’ll talk about me without acknowledging that I’m standing two feet from them.

For example, this morning I was trying to figure out how to install adobe flash player correctly because usually a bar will pop up at the top of the screen, indicating to click and allow activeX controls (as you all know). It wasn’t working because another bar was blocking it, and it would cancel both if I canceled the bar that said “you are running Internet Explorer with a disabled addon” (even though all were enabled). My step mom comes over and asks what my step dad — on the laptop next to me — is doing. Then she asks “what’s he doing?” instead of saying “what’re you doing?” to me.

Reasons I’m paranoid that I might be slow or mentally retarded are:

1.) I barely talk
2.) I never show emotion, rarely you’ll see me without a blank face even when I’m talking
3.) I sometimes forget things, like when doing something instinctive without much thought I’ll forget what I’m doing (like right now I had a #4 in mind but forgot what it was while typing #3)
4.) I rarely raise my hand in class
5.) Teachers give me different reactions than I would expect to be given during certain situations
6.) I’ll be in a group, say me; my father; my stepmom; and my step sister/biological brother. They’ll all be talking and won’t talk to me until I say something. When I say something, nobody responds. A few seconds later, somebody will bring up a completely different topic than anything related to what I had just said a few moments before.

I apologize if this is long. I really don’t think I’m retarded or slow, because for one thing, look at how I’m typing. I don’t think someone slow or retarded could type like this.

I know the question was simply “how can I tell if I’m slow or mentally retarded”, so I’m not going to dread on about how I pretty much know I’m not mental. I probably just have a social anxiety; which, in turn, causes others around me to believe I am retarded.

So, after that big wall of text, how can I tell if I’m slow or mentally retarded? Are there any online tests?
Oh yeah: I also was in Speech from kindergarten to my 6th grade year; in which my teacher didn’t want to see me go on through my entire career in speech class. That might just be an issue that causes my social anxiety or (on my negative side of my thoughts) might be another symptom of mental retardation.
