Hey Lucia, those are good achievements, as you have probably noticed - depth changes everything.
From what I've seen equalization is the number 1 set back for most who begin diving vertically.
A few pointers:
Learn the frenzel - use Eric's document, you have enough pool time to make this perfect.
Take notice of your head position - looking towards the bottom usually messes with equalization, try looking at where the horizon should be, or even try looking towards the surface when going down.
Equalize VERY frequently - the bigger the pressure difference between your middle ear and the surrounding the harder it is to equalize. Negative pressure in your eustachian tubes narrows them. Equalize 5 times a meter if you have to, descend slowly, first let your euqalization run, then work on descent speed and pace of equalization.
If you hit an equalization block - stop descending!! try again (never forcefully!!) and if it doesn't work just enjoy the depth you are at and try again the next dive.
I hope you'll have the chance to try again soon.
