I am the interest of 2 guys. Please help?

I seriously have a problem and it's heartbreaking because I know these 2 guys for a very long time and the worse thing is that they know each other too and are friends from school days. Both have a romantic interest in me...guy A is studying engineering, is very respectful and quite funny and can be romantic,... show more I seriously have a problem and it's heartbreaking because I know these 2 guys for a very long time and the worse thing is that they know each other too and are friends from school days. Both have a romantic interest in me...guy A is studying engineering, is very respectful and quite funny and can be romantic, the same applies to guy B it's just that he studies medicine. Both are good looking and great people that come from good families. I don't know how to pick between them. I'm scared of how this will end.
