Unhappy toddler?

My son has been whiny and clingy to the point that I am going crazy. He has always been super needy, but I feel like he should be gaining a little independence at this point. I can't walk away from him without him screaming. I try to include him in "chores", but aside from that it is hard to get anything done. He won't play independently, he doesn't want his dad, and he just always seems unhappy unless he's clinging to my neck. All the effort I put into him, I want it to mean something. I try really hard to be a great mom. I feel like I've done something wrong. I already have a ton of mom guilt because I work full time and we only get what seems like a few hours a day together, and we spend those few hours so stressed out with each other.
