I have attended a Baptist church regularly for the past 6 or so years. Due to recent life event, I'm now questioning some of the doctrines.
I hope you don't abandon the most important doctrine: That Jesus Christ died for you so you can have eternal life with the Father. When you have decided you don't want sin in your life and you accept the free gift of salvation, you accept the righteousness of God through Jesus Christ. No other doctrine is more important. No church denomination takes precedence over the Gospel.
My grandma, who is Hindu, passed away and I got no support from the church or my Christian friends
I am so sorry for your loss. There are many people who pass away every year, but there are none as uniquely qualified to be your grandmother. Make no mistake, she was one of a kind. There will never be another human being created who can take her place. It's just too bad your church didn't recognized what a uniquely challenging time it was for you.
You are not alone, though. The modern church leadership has decided in recent years that it is much better to fill the seats than to disciple its member. And part of discipleship is caring for the individual disciple. So many are leaving the church because of this.
But I have good news, you are still His disciple even if you aren't currently active in an institutional church. I would just remind you, as the Apostle Paul reminded the early church, to not forsake your meeting with other Christians. I would encourage you to either find a suitable church home, or at least join a small bible fellowship in your area. You may have to start one yourself. I hereby give you express permission. Just be sure to bring your bible! In the mean time, I would encourage you to frequently engage with those on this forum. I love how the people on this site are willing to talk about God. I couldn't find that going to "church." How sad.
Now, I'm more focused on reading the Bible and deciding for myself.
I'm glad you are still reading your bible. I would encourage you to stay focused on the four Gospels, for now, and just hang on every word Jesus spoke. I am curious, however. What is it you have to decide for yourself? Is there a major decision you feel you have to make concerning God?
I find myself leaning more liberal now on quite a few issues, but not sure if it is scriptural.
I would encourage you to completely ditch the politics. After all, Jesus didn't worry about overthrowing the Roman government. Instead he told his disciples to preach the gospel in spite of it.
Anyway, I hope I've offered some encouragement for you. Unlike church pastors, my door is always open. If you want to correspond, I am here for you. You don't need to go through ten gatekeepers. You don't even have to fill out a phony contact form.
In closing, I have found that serving others is a great way to move forward from difficult situations. May God bless every aspect of your life.
