100% atheism. Was raised some kind of protestant I forget which one, and derived tremendous spiritual and psychological relief when I realized all of that was absolute nonsense at the age of 9. I knew I was gay at the time and wouldn't come out until I was 18 or so, but my life just got a lot easier when I removed religion completely. I also recall discovering increased moral agency -- as a Christian I had been taugh…
Having gone through this process myself years ago I can attest to this, while also I must give my strongest recommendation that you eventually begin looking for a spiritual practice. Organized religion's wild success among humanity is a great testament to it's Darwinian fitness, and it undisputably provides many benefits to believers that you most definitely lose if you simply subtract it from your life.
Many atheists struggle with finding a replacement for those benefits without adopting magical thinking in some other way, and I sympathize with this. But once you have had a few years to distance the pain of religion, I highly recommend looking for a routine source of spiritualism in your life. Sam Harris advocates for meditation which seems to be the most prominent atheistic alternative, but it doesn't come by default with many of the benefits that organized religion does (community and ceremony to just name a couple off the top of my head).
Whatever time and effort your parents and family invested into religion, I recommend taking some portion of that and investing it in your own spiritual well-being. And as a disclaimer to all this: I too am atheist, I don't subscribe to any magical thinking, and I am co-opting the word "spiritualism" significantly here but I can't think of a good alternative. I don't actually believe "spirits" exist.
