Can someone who believe in theory of atman/self end ( general ) sufferings by Buddha's advice?

I believe that a soul exists due to my religious background, and my religious scriptures say that those who shall not have faith(in existence of soul and few other things) will face extreme sadness in the afterlife. I have many sufferings in life, including emotional, physical, etc., and I have been facing this by constantly telling myself that I will enjoy the afterlife, but now I am doubtful of any kind of afterlife at all. So, I decided to follow the teachings of Buddha, as they do not require faith in something that is not knowable to stop suffering. I do not want to convert to Buddhism, as I am a little sure but doubtful about what my scripture says about the afterlife is somewhat true, and it will create a problem in my family. ***Main question: If one believes in atman/self and also believes that the teaching of Buddha will end suffering (except for the teaching of no self). Will Buddhist teachings to end suffering be good for this type of person? Are there sets of Buddhist practices to end suffering that I can follow even after believing in a soul/self, or do I require to abandon my belief in the existence of a soul? Also, what are the Buddhist practices to end suffering in which one cannot do till he does not believe in the absence of self?*** Request :Answer in simple terms as I have very basic knowledge about Buddhism and please avoid commenting on my faith.
