hi preeyoo7 how are you, let me tell you there is only only one god, or you can say that there is only only one supereme in universe, there are are many names of that supereme power.that is a good way to remember him by chanting mantra, but he is only one (by the the reference of rigveda) and also by physically,so why should'n you concentarte on him by one name and by one supereme power,moreover you also change your nature towards people around you,just be kind and genuine to people around,be truthfull and honest towards god and people around you and after that ask god anything you want, and make your thinking that he is the only one that can help me out and then see how he gets you rid of you by your problem, i am also die heart worshoper of lord SHRI RAM , in my early life i am also worships every god,but afterwards i realise that i can concentrate only in lord SHRI RAM that does'nt mean that i am repecting other god and goddess,for that we all have to study our relegion briefly, ours is vast culture and thinking
thank you
