(Fatwa: 289/225/B=2/1439)
Whatsoever faults you committed in your childhood it was bad and you remained ignorant of the Holy Quran. Now the solution is that you must take out one hour in the morning and one hour in the evening and learn to read the Holy Quran before any good Qari. You should read it attentively and work hard then in-shaAllah, you shall become able to read the Holy Quran correctly within one or two years.
Allah knows Best!
