At first I was on your side OP when I first found this, I genuinely wanted to help. I read the whole thread, I read every post you made. I looked over this whole thread to help you. Im going to say something, it's going to be hard to hear, but it's true and deep down you know it as well.
You have done nothing with your life after high school. No university, no trade school, no work/study program, no internship, no volunteering, no (even though I'm an Atheist) church involvement, I read your skills list and you never mentioned one legit certification (did you just take a class to be knowledgeable or get certified - also you know every year or two you have to continually go through the recertification process right?), dude you have wasted the last few years of your life, doing what? You say no alcohol or drugs, but how long has that been? You are not filling us in on some 'gap' wasted for 4 years, there's something there you haven't said. You say you work out six times a week, so I get it you like he way you look, well no one else gives a shit about that, you are not a model and others only care how you look like on paper, you say you're dedicated, but that's bullshit. Your physical mentality is strong, but your mind can't even curl 10lbs.
You have shown us you have accomplished nothing sense high school.
I'm sorry I know that sucks to realize man, but it's true. What's one thing you have done after graduation that an 18 years old couldn't do in less than a summer? I'm seeing nothing man. You have been a freeloader on someone coat tails, either your parents (maybe they kicked you out and you are writing this post), maybe a girlfriend, grandparent, or family member.
You don't have a job, but somehow have a car, pay car insurance, live somewhere you ARE NOT PAYING rent, you get gas money and a gym membership, this isn't even going it on your food or supplements. You are a freeloader man, someone is consistently supplying you money.
Here's the best advice I can give you, Do Something, seriously Do Anything. In your life you have never actually done something. It's a hard reality to face that you're a loser.
