Lou,
I am so sorry you are feeling this way, I was in your situation almost 2 years ago to the day. The first 6 months were so rough for me, I had a 20 month old and our new son came home at 1. He was also very clingy, I couldn't go to the bathroom alone, throw something in the trash, etc, he would chase after me screaming. If I would pick him up my other one would need to be held, jelouse. The boys were constantly fighting, same thing, one would walk by the other and hit one another for no reason, my new son at the time used to crawl right up to my oldest and bite him in the leg for no reason, multiple times a day! I swear there wasn't a minute in the day that someone wasn't screaming and crying, it really does ware on your nerves. My youngest is very sensitive and attachment was hard for him. It wasn't probably until 7 or 8 months until he would say he loved me or kiss me. I remember one day in the grocery store, I used to put him in the front of the cart and I would always hold his hands when I pushed the cart, he used to force my hands off of his, but one day instead of forcing my hands off, he leaned down and kissed my hand. I think I stopped right there and looked at my husband and said, oh my goodness that was his first kiss that he initiated on his own! It was the coolest milestone that I will never forget. So my point is, it takes time for both kids to feel secure in the new situation, it is such a change for all, and Essie is just really scared. Find time for yourself, you have to or you will go crazy!!
