I couldn't agree with this more. I think a lot of it has to do with the age. The kids just don't want to do the work and they get lazy. And they are moody. And they have a sense of entitlement. No electronics around when I was a kid. I had a brother like your son... 15 years later, no need for psych eval. He just doesn't put forth the effort if someone will do it for him.

Ups and downs in moods are normal with teenagers. I have one. It doesn't mean that I think she needs a psych eval. I think she can be lazy sometimes and doesn't want to hand in homework. Bright, bright kid. Straight A's. One term she was pulling D's. I knew she was capable of more. I hounded her, gave her incentives. Took away things that I know would affect her when they were out of reach. Checked online to make sure every assignment was getting in. Communicated with teachers. She pulled those D's up to A's. Still moody? yes. Could she sleep all weekend if I let her? Oh yeah. Any signs of mental illness with a cookooo mom in the house? Nope.

And this is going to sound very harsh, but I think your son is playing you.
