Hi Wally ~ Yes, you should see someone, before your emotions are so deeply hidden that you'll never be able to draw them back out again. Our minds have a way of burying things deeply and believe me, you don't want your emotions to be that deep!
Talk to your medical doctor ~ he can refer you to a good therapist. He will know who is the best for you. While this is probably related to the breakups, some of this could even go back as far as your childhood -- one never knows!!! So try therapy -- you won't regret it!
God bless and please keep us posted from time to time as to how you're doing, will you? We'd REALLY like to know! Take care, Wally.

Hugs, Lee
