I still don't have the breathing down yet, but getting better. I train with a snorkel to get my form down, which someone else also suggested for you. It's great to get in the exercise and not worry about the breathing.
It appears you may have expectations that are too high and not achievable at this time, so you are frustrated and "fed up". Lower your goals to smaller steps that are achievable with practice in a couple of months. Then, move on to the next small step. Be patient. Find joy in what you can do.
Wonderful words we all should take to heart, in swimming (yes, drills and all!), and in life.
