I need to thank someone!
I posted with pics of my sad sunflowers asking for help. I got a response and read it at work quickly, and went back to read it thoroughly after work and it was gone. The advice was to water 3 times a day and put down mulch (all I remember). Just watering 3 times a day really helped and now both remaining plants now have 3 and 4 beautiful blooms with more starting to show blooms! I will share this within my original post, I just wanted to try to reach this person and thank her for great suggestions!!
