Since My boyfriend parents were killed in a car crash he has become very clingy to and he is NOT eating?

sorry for his loss

he may need professional help to get through the death of his parents, a counsellor... he is young and just had both of his parents taken away from life, in a horrible way.

also, he may be just clinging to you more so now, because of the accident that claimed his parents life's.

tell him your worried about him and try and get him to go see someone... give him time to grieve aswell and stay with him, don't give up on him, hes going through a very horrible time and needs all the love and support he can get

If my parents were both killed in a car crash at 18 I would be completely shell-shocked. Clingy is to be expected. The closest people in his life have been ripped away from him. He has a void where that relationship was to be filled. Be understanding, even if you have to tell him it bugs. It will probably take him years to fully fix his head. If he continues to college, most campuses offer free psychological counseling. Normally I'm not big on psychologists, but in his case he should seek the option. He also needs to be wary of drugs and alcohol. They're phenomenal in masking the pain and making you forget, but it does nothing to move past it. It just delays the problem. It's not that you stop taking the drugs and alcohol that you can finally truly move on. In dealing with my own unique problems growing up I had to stop the substance abuse before I ever moved past.

he is going to be clingy as he has lost his parents and doesn't want to loos someone els he cares for, eating less is natural and he should start eating small things like chocolate bars and stuff and work back up to having meals

school should be one of the last things he should worry about, he just needs time to recover from it witch may last a couple weeks to months or even a year or so, so just you help him in any way you can.

The only thing you get do is to give him a lot of attention and sympathy. The way he behaves is to be expected after such trauma. You need to be very patient and give him time. You need to encourage him to eat even if it is just junk food, Time will heal!

He'll be okay after the mourning stage.

he needs to see a bereavement counsellor

Please get him to seek help, support and counselling.
