My advice that I gave in the other thread would apply here too. Study each of the religions, then pray and ask God what is right. You can pray about particular doctrines or beliefs too. You can even ask God about whether you will be punished if you change your beliefs. Just pray sincerely about your questions, and listen for an answer.

I am Christian, and I find a lot of good in Buddhism and other belief systems. I would study them more if I had more time, because there is a lot to learn there. I have a lot of appreciation for meditation and alternative medicine. Those things definitely have something going for them. I enjoy yoga, and I'd like to learn about Tai Chi. That energy is very real. The universe is full of energy. Prayer is a meditation and energy practice too - it's just that we don't necessarily think of it the same way.
