It is going to suck ass. It will get better. I promise. You said it in the last line of your comment. 15 minutes gone by. Sometimes you will have to take it 15 minutes at a time and that's okay. Shit man, you can do anything for 15 minutes, right? Then you bite off another 15 minutes... and repeat..
Hang tight to the site in these first days, read all you can, continue to re-up your motivation, post roll EVERYDAY, and reach out to your quit brothers.
You can do this.
PM me anytime you need something.
