Help me please! urgent! eyes won't follow my rig? also problems with controls

[gabrielburgosgl]

Hi! I'm a total rookie, first-time poster, very long-time lurker. I'm very distressed as I'm working on my first rigging project for school and I feel like I totally messed it up! The rig I made "works" perfectly, but once I skin it, aside from painting weights issues (of course) some things are just working very strangely. I need to turn it in on Monday so if anyone could shed light on this I'd super appreciate it. 

FIRST PROBLEM:

I skinned the eye joints to the eyeballs, and the eye controls are parented to head control, however, they will not follow the head and just go crazy when I move them... I've tried different approaches with no luck. 

SECOND PROBLEM: 

I made a control for all the lip joints. They move together just fine. However, when I turn the head... the joints go crazy. 

This is because I set the lip joints to make themselves smaller when you move the lip control as to follow the head structure... but now I don't know how to avoid this problem...

other than this, everything works just fine, but I need these two things to work so so bad. Please help me! if anyone would rather have my discord I'll gladly pm you with it. thank you to everyone in advance!

It would be better if you attached the scene.
