Tbh if you are changing mask suit etc every time you are going to have trouble.
First thing is get a mask that fits. Spend a couple of hours in a shop trying a bundle of them until you get one that works. A good shop will understand and help you.
Second get a drysuit that doesn't leak. Drip you know where the leaks were? If they were due to the neck and wrist seals that can be worked on (new seals or adjustments).
Staying warm on the surface is hugely important. If you were cold going in it will just get worse when you are in.
