Vegetarian maybe

Thinking about becoming a vegetarian. I've been reading things and idk I just am too much of an animal lover and always have been I actually just feel sick thinking about how long I've been eating meat...the way those animals are treated I just ugh idk..then again IDK the first thing about being vegetarian and ik it'll still be hard! Can anyone give suggestions or advice please? 
Also, is there any difference in only eating white meat vs eating white and dark?
