We have seen these changes and it's because of the stress, trying to burn the candle at both ends, trying to be young and not eating properly. He will probably look tired at times too and yes, they tend to be sick quite a bit. It's a bundle all wrapped up in depression. At some point, further down the road, he may begin to look a bit better...but that's going to be a while.
Hunny, take a stroll around some of other threads. You will see that many of them turn out just as they feared they would years down the road. They become the mirror image of the person you knew and loved (exact opposite). Also, they only allow you to see them as they are at the moment. When they are out and about w/others, the nicer mask comes into play and sometimes, they will reveal their true selves to the OP, but it's a difficult juggle of being the true self and the mask of happiness. It takes a lot of energy to do so.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
