Irritated

So I had my son about 6 months ago. Ever since he was born he has been held a lot ecerytime I go to a familys house, inlaws, friends, when we get visitors, etc. I feel like people use my kindness to walk all over me. Someone is always hogging my son and I dont know why it irritates me so much.. I understand they want to see him hes loved by many people. Im just still so sensitive and emotional. Anyone else experience this?
