So essentially, I'm supposed to be losing so much coolant so quickly? Within the month that I've been using my A/C, I've lost about half of my coolant. That can't be normal just from drainage so I assume my core must be bad. Plus, my cars interior started smelling like ^@&% after we noticed the leak.
What does a heater core bypass do exactly? I live in Florida so of course I need my A/C, and it being cold at that. I want to try this myself, and if I mess it up I always have a backup A/C and auto repair mechanic I know fairly well.

The bypass:
You disconnect the hoses to the heater core, then you connect the
hose ends together so the coolant just flows freely from and to the pump,
this is called, a bypass. Since you're in FL, you probably never need
heat? So, you don't need a heater core.. So, take it out of the loop.
This will save you lots of time and money over replacing the core. It
will have nothing to do with the A/C, so it's fine.
HOW you connect the the two hoses after you remove them, is up to you...

After only sitting there for a minute there was a huge pool of water/coolant under the car. It didn't have a strong smell of coolant to me but I've also been smelling it all week in my car. Gonna go get some parts for the bypass and thank you for your help!

Yeah, but the water I see coming out of the drain is clear, not orange coolant rusty
looking color. You may have a coolant leak somewhere else, but that is not coolant
coming out of that drain, it's much too clear. The other moisture on that black line,
where you said, right up here seems a little wet, is just condensation, that is the
A/C line to the condenser. Your core is NOT leaking with what I saw in that video.
Not unless you are running water and not anti-freeze.
You should look elsewhere for a coolant leak... That's not it.. I mean, you can
try a bypass just to be sure, but from what I saw, that's not coolant. It may leak
when at higher RPMs, or when you shut the motor off and pressure builds up,
but that was not coolant coming out of the drain.

Ugh I'm sorry about how ignorant I am about it, I'm sure it's like talking to a brick wall lol. However I will simply go over it again the next couple days, I bought some more coolant and am just gonna run it for a couple days and see what I can find. I'll respond with what I come up with!

No problem, we'll keep after it...
As I said, the leak can occur at higher RPM, or when you shut the motor down
and the pressure rises a tad.
So, as far as the video goes, that's simply condensed water from atmosphere
moisture that accumulates, and drips off the condenser. It's clear, not coolant
color, so so far, it's not the core.
With the motor running, idle, check the reservoir to see if it is bubbling. If so, that is
a head gasket.
