I just want to say that horses are healers of the heart, soul, spirit, mind..
Riding horses, being around horses.. interacting with them is absolutely 100% amazing in every way shape or form. Blind shouldn't stop you, you can do everything that every other person can do, with help :)
I hope it becomes a reality for you, just find the right person that is patient and willing to explain every little thing to you.
See this is why I wish people could teleport. I'd be so willing to help you get introduced to horses.
Best of luck, my friend! And you gotta love technology :)
P.S: Not even Hollywood can depict the amazingness of being on a horse. You gotta experience it first hand! :)
