You are not alone, I had taught myself using real flite sim and I have an alpha 40 and used the PT 40 on the sim, I have many flying parks by my area but my parents have 300 acres in wisconsin so I practiced on the sim atleast 2 hours everyday for a month or 2 and everything went fine, just make sure to do all the pre flight checks and make sure to turn on the tx before the airplane as you will un bind the plane and as soon as its 10 feet in the air goodbye to any control you will notice that happen if you see a orange blinking light inside the plane when you put the wing on, to fix this turn the plane at tx off and turn the tx on then wait a second and turn the plane on. Whoever said above about low is dangerous is very correct, GET ALTITUDE, see I have my real airplane and heli certs both VFR and IFR and takeoffs are where the most crashed happen as you have no altitude to fix any mistakes, and god forbid if you just get to 6 feet then land and its out of trim you will take it home in a trash bag, take the plane off get to 200 feet or so and trim that plane out, do NOT do what you where going to do. You will be fine, just have confidence and try and stay calm, you developed alot of muscle memory from using the sim, so just pretend its the sim, only this time you have the risk of wrecking your plane rather then hitting restart. Good luck and again I did mine all by myself and now am flying a pulse xt 60 which actually flys better than my trainer and its an acrobatic low wing but it lands so slow and does not want to float. I am moving my way up to my top flite p-51 with a saito 100 series in her after I get one more plane, so the p51 is sitting in the basement waiting. Good luck and think POSITIVE.
