Lil, I am sorry this happened. He clearly does not want a job and it could be drugs. I know you think he quit, but you don't know. His "I can't do anything right" is part of the difficult child manipulation song, in my opinion. They seem to all say it because they are actually quite smart and they know us well and know that if they act pitiful, we will feel sorry for them and give them a break. It goes along with "this is all ______s fault, not mine", "you were a rotten parent and that's why I do this and the others difficult child manipulation tries, the most serious one being, "I guess I'll kill myself then." Pawning stuff is most often due to them not having a job combined with needing the money for drugs.
Lil, if he really wanted to work, he would have gotten a good night's sleep, set the alarm to wake him several times or maybe even asked you if you wouldn't mind waking him up so he won't be late. He would have called in on his own and gotten the doctor's excuse. Sometimes we just can't face or don't want to face what our adult child is and that there is rarely a quick change (in some cases there is, but something big has to trigger it).
If you can, try to detach and not personalized what he did and talk to your hubby and decide if you are ready to do something about his behavior or not. Don't think about it all the time. That won't change him. Fighting with a difficult child is like rolling a heavy rock up a mountain and never being able to achieve your goal. I used to talk and overtalk to my son because the things he did were both sneaky, elusive, and dangerous. I never got anywhere. I got a bunch of lies, crying, accusations toward me, and no results. My own opinion is to minimize confrontations and abstract talk to our difficult children. If we have something to tell them that is concrete such as "Here is a contract. You either sign it and do everything on it in three months or we are not allowing you to live here", well, then we are telling them what we expect and the consequences. Yelling, anger, threats we never carry out and letting them have their slap at us with verbal diarrhea just hurts us and doesn't help them. I finally will never engage in that sort of talk again. Not with anybody. I learned. Yes, it took a long time.
Hugs for your hurting mommy heart. Try to be good to yourself. You're a good person and a good mother and I hope you can find peaceful moments and happiness.
