Effects of spanking?!

Okay I may just be crazy but I was spanked as a child and it makes me wonder a lot about the effects of spanking, like I have a really bad temper and anger issues. Sometimes I find it hard to control myself and my feelings, I've been working really hard on it but sometimes I wish I wasn't spanked as a child so I'd know if it's my fault I have anger issues or if it stems from being hit.. I feel like if my parents used a more gentle approach at discipline maybe I wouldn't have these issues:/ idk just a thought.
