people in trauma situations need close bonding, for this reason there are "trauma dogs" (not sure if this is the correct english translation). You are not in trauma but i guess you have one thing in common, you need oxytocin. An easy way to get it without human contact is to get a pet like a dog, cat, hamster oder else.

give it a try with an animal from an animal shelter, if it doesnt work, give it back.

a close contact to an animal works on a much deeper level then any therapy. i can tell since i have 3 cats, good luck
