Possible learning disability?

Ok, I completely understand this is an odd thing to post so i get that puzzled look your probably making.

Anyway, I have a learning disability and besides the anxiety its caused and having to be held back in 2nd grade its never really bothered me or been apparent to me until recently. All through school i have had an IEP and have had to be in the special ed classroom,( i know what your thinking and not like that) you would actually never know meeting me that i have a learning disability. I have friends, 2 children, a husband and a job, only my husband knows about it because i talk to him about it.... a relatively "normal" life... up until recently i NEVER questioned why i had to be in the special ed room. I mean i knew i had trouble remembering things and it took me alot longer then others to learn things, I was bad at (and still am) every subject in school.

Im 27 years old now and life right now is so hard for me. The only thing i seem to be good at is being a mother. My job is starting to get more demanding with paperwork and such, with all this change its been hard for me to keep up. Not only that but my 4th grader is bringing home homework that i cant help her with!(yes 4TH GRADE homework!) This is completely embarrassing to me. Im starting to hate my job and my 9 year old is starting to see me struggle and I am ashamed.

I feel like i cant move on in life because whatever is going on in my brain is holding me back. I want to know exactly what is wrong with me or if what i have has a name or if its anything at all (sometimes i think im just being lazy and I need to try harder). Iv called my high school hoping to see my file but they dont have it any more. Iam to embarrassed to go to the doctor but now im thinking it may be the only way to figure out whats going on and how to get the right help?

Any suggestions and/or simular experiences?

Please be kind.
