No Advice is the best advice .

At this stage, it is better let him figure out himself, and try to avoid give him any advice.

If possible, give him positive feed back on whatever he does at home, appreciate his affort. Avoid critisize him at this stage, not matter what.

Being supportive is all he needs at this time, a warm/happy home would help too.

He need to talk to a man, a close friends, or his formal professor...but not you.
