posts full of typos!!!

I rarely get on the computer at home, refuse to blog at work and use my smartphone like a second skin. But this is driving me CRAZY!!!!! I have tried to edit this post 10 times already and just finally decided to re do it.
When I post from my computer, the formatting it off!!! It appears like one big paragraph.
Then when I use my phone, it formats perfectly, but the dang nab auto inject keeps putting in things that I don't want and I never catch it or can figure out how to stop it!!!!!
Needless to say, I have to put things into my phone for the right formatting and then log on to my laptop to make to corrections. Oh, did I mention that every time I try to correct a typo on my phone, I have to dance around the screen to get the cursor where I want it and good luck trying to get it back to the end!!!

This is driving me crazy and I have to find a solution!!!!
