It's unfortunate that some children have to go to schools the like of which you mentioned. Islam has instructed us that children should be free to play and never be forced to learn anything, until they reach a certain age (7, in most hadith). Even then, the learning should happen with love and patience, creating a thirst for the knowledge. I hope that it is a lesson for all of us in how we deal with our children.
The most important thing regarding the holy Quran is to be guided by it. This requires a very strong loving attachment with the holy book. Any means you employ to arrive to this is beneficial and any thing you do which will not help this must be avoided.
So, having your own personalized Quran, reading it without putting pressure on your self, enjoying learning from it, slowly memorizing verses that are very interesting to you, etc.. Anything that you find is helping you to build a connection with the holy book and through this you are being guided, is a blessed act and inshAllah accepted in the eyes of Allah (swt). Don't feel depressed or negative. The door of His mercy are always open: it's for us to take the step inside and enjoy from His blessings.
