Hi Xcalibur girl.
I am a student and I feel this way about every other lesson. I am currently stuck on touch and go's. That's fine, the most important thing I think.
You will keep going and do fine because you want that accomplishment that so few have, not because they can't do it but because they don't want to put the effort in.
Listen to your instructor, he believes you can do it.
Ignore anyone who tells you it's time to rethink it.
You already know you are cut out for it because you have the one requirement, passion.
I found this at a corvair engine conversion site.

just substitute the word pilot for builder etc.
In the years that you will work on your creation, you will have at least 200 people tell you that you are doing the wrong thing. you should quit. This will not just be in the form of a coworker or a brother in law calling your creation a ‘death trap’ repeatedly. It will also come in the form of other fliers who are EAA members, but would never even fly in a homebuilt, far less create one, telling you just to buy a plane, to give up on self reliant craftsmanship, just because they did.
.
When people offer you this unsolicited advice, trying to have you quit, think of a man, with a destroyed reputation, with no one looking for him, held captive and tortured in the jungle for years with out a single act of kindness or human compassion shown to him, not a single friendly word spoken to him. All he had was his inner belief that he was on the right path. Politely nod and ignore them, and to yourself think “My name is “ and “I am a Homebuilder.”
I'll make you a deal. If you stick with it, I will too.
