Ok I need some help/advice!

[Fisherboy]

I'm 13 and getting a single person opentop kayak for christmas!Plus a paddle and a folding anchor!I have canoed some but never kayaked!I live in North AL and have many creeks and lakes to practice on!This kayak has some fishing gear allready installed (I will add more)!
I go to Mobile AL 2 times a year and Daytona Beach Florida 1 a year!
I want to fish in a spot in Daytona where the tide changes often and I don't know how swift it is but I know where I would launch it is fairly swift at the fastest point!It is a mile upriver to where I would fish!where I would launch is oh a half mile to the ocean (this area is where a river empties into the ocean )! Where I want to go is a mile upriver or down depending on tides!I mainly want to fish for flounder and redfish and maybe some snook!The tides if played right could be use to pull me upriver to my holes or down away from them right???
My question is could I safely paddle upriver , fish , fight the tides , and return in one piece???There is a lot less tide a half mile directly upriver!
And in a normal tide going aginst me could I even paddle aginst it???
Could I get tide charts and use the tide to get upstream???
I will wear a pfd and carry a signiling system and first aid stuff!
So at age 13 by myself could I safely paddle under these conditions???
I have fished , hunted , trapped , and swam for 10 of my 13 years and do have a little expirence!
Also my parents believe there are gators that might eat me please tell me and them this is wrong!
I know there are gators in the area but not common espically in daylight!
