You are most definitely not "whack". Everyone grieves in different ways, and the process really is the mind's self-protection mechanism going through the process of feeling the loss and eventually accepting it so that one can go on with life. With these horrible tragedies all in quick succession I don't think it is unusual at all for you to be sort of numb. You are probably in the place you need to be to keep from being overwhelmed. It does sound like you are grieving with the "expected" feelings and maybe those feelings are just naturally being held in check.
The one thing that is for sure is that everyone grieves differently and you can never try to put "rules" or expectations on grieving for yourself or for someone else. The "stages of grief" I've posted elsewhere are guidelines to help understand the different emotions that one may go through during the grieving process, they are meant to help understand but not as a "roadmap" as to how to grieve "properly".
It is not a bad idea to get some support for this, we can provide support and understanding if you want to keep posting here. If you have access to a support group or therapy that may be able to help guide you through these emotions as well. But there is absolutely nothing "wrong" with what you are experiencing now, nor is it unique.
My heart goes out for you and for your family and your friends family after these horrible circumstances. It is good that you have each other for support through this and we are here to help too.
