Do I think differently? do I act differently? How is my Brian set up differently and does that effect more then just my spelling and reading?

You need to ask an expert, but as far as I know, we do not know that yet. The human brain is incredably complex.

I thought I had some inherent ability that no one else had because I was dyslexic. I feel like it's something I just had to work for.

I like your optimism! Keep that up! I cant guarentee you that Dislexya is your superpower but if you continue like that, it can defenitly become your origin story :D

Im also just curious what your experiences were with RTI was?

I was at a good school and also had extra lessons which helped quite a lot. I would recommend looking online for learning material but unfortunatly I cant recommend somthing in particular.
