Asalamu alaikum wa rahmatullahi wa barakatu,
Like many others here, I was born into a muslim family in a western country, however, in my teenage years I rebelled against islam and started taking into account different ideologies about life and what happens after we die such as studying buddhism and etc. I stopped praying and fasting and remembering Allah سُبْحَانَهُ وَ تَعَالَى and started to commit every major sin you can think of, I basically became a kafir (Istaghfarullah).
