You could have one, ten, or a thousand people on your side; but if you don’t believe in yourself, then it doesn’t matter how many are present. You, of all people, must be the first and most strongest supporter.
You’re doing an absolutely amazing job. You really are. Sometimes you may screw up, or make mistakes, but we all do sometimes. Just keep up all of your amazing work, friend, and remember that one setback does not erase all of the good that you’ve accomplished.
