Help for my son's emotional issues

I have a wonderful and smart 6 year old boy who is extremely sensitive. He doesn't like tags in his clothes, he thinks some toothpastes are too 'spicy' and the tiniest cut will cause him to cry. This morning he was upset that his pants didn't fit right and that sent him spiraling out of control and he cried so much that his pale skin on his face was red rimmed around the eyes.He told me he could not stop crying. I have considered consulting a psychologist, but I was exactly the same way as a kid emotionally. My parents said that physically I was the opposite of sensitive. I would have an ear infection and never complain, but I was very sensitive emotionally and would cry easily just like my son.
I just want my son to be able to cope with life better. He is easily frustrated when learning anything new and usually ends up in tears if he does not grasp a concept or sport easily. Overall he is in good health. Right now he has a reddish rash on the left side of his mouth ( about the size of a penny)and a few sprinkled under his lower lip which does not bother him. He is pale and of average height and weight perhaps a bit slimmer) and has sandy colored and very thick hair. He loves to build things, socialize, but needs time to rest and 'snuggle'. Thank you for any advice you can give.
