I'm bad at comforting people

So my boyfriends mom passed away 2 years ago today.. We started dating the January after she passed so I never got to meet her. He never acts really sad about it but today he is down because it makes 2 years. I'm away at college so I can't be with him today and I just feel really bad about it. His family now isn't all that great and supportive so I just really wish I could be with him today! Even though I really suck when it comes to comforting people I just feel like I should be with him. Posting this because I just need to get my guilt out...
