SOLVED:
-I had virtual environment inside my home folder. That's a 'no no' unless I
grant apache access into my home folder's environment directory. Did not
want to do that so I created a virtual environment inside my application
folder (see 'env' in the output)
-Because of that ^, I was needing to do 'sudo pip install flask' and sudo
pip install mod-wsgi'. That's a big security 'no no'. This was giving me
grief for days. Thank you, Graham Dumpleton for all your help!!!
Here's my configuration as it might help others:

Here is my site configuration in the apache config file. Note that the
'LoadModule command is not inside the VirtualHost section. It's in the
specific location I show:
LOOK FOR THIS SECTION IN THE APACHE CONFIG FILE:
# Dynamic Shared Object (DSO) Support
#
# To be able to use the functionality of a module which was built as a DSO
you
# have to place corresponding `LoadModule' lines at this location so the
# directives contained in it are actually available _before_ they are used.
# Statically compiled modules (those listed by `httpd -l') do not need
# to be loaded here.
#
# Example:
# LoadModule foo_module modules/mod_foo.so
#
Include conf.modules.d/*.conf
#
#THIS NEXT LINE IS WHAT MAKES APACHE LOAD THE MOD_WSGI MODULE THAT 'LIVES'
IN THE VIRTUAL ENVIRONMENT
LoadModule wsgi_module
/var/www/myflaskapp/myflaskapp/env/lib/python3.6/site-packages/mod_wsgi/server/mod_wsgi-py36.cpython-36m-x86_64-linux-gnu.so
#THIS NEXT SECTION IS ADDED TO THE END OF THE FILE
<VirtualHost *:80>

#ServerAlias www.myflaskapp.com

This is what myflaskapp.wsgi file contains:
import sys
sys.path.insert(0, "/var/www/myflaskapp")
from myflaskapp import app as application
This is some output about the virtual environment. IMPORTANT - mod-wsgi
must be installed inside the virtual environment with the virtual
environment active. Once installed, you deactivate the virtual environment.
In this output I am just illustrating how I get into the virtual
environment to see what python modules are installed in it. Then, I just
deactivate it as apache does NOT need the environment to be active in order
to use the module.
