In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
If you broke the fast of Ramadan without a valid reason you will have to make qada (repeat the fast that was broken) as well as to keep Kaffarah (compensation). Kaffarah is to keep 60 consecutive fasts. [1]
When a person becomes baaligh (adult) it is expected for him to know the fundamental duties and obligations of Shariah. Ignorance of the Laws of Shariah is no excuse.
You are young and Alhamdulillah you are becoming more conscious of the Laws of Shariah. Muster the courage and keep the 61 days fast, 1 qada fast and 60 kaffarah fasts.
And Allah Ta’āla Knows Best
