My condolences on both of your losses. You asked if you should talk with family and friends about your losses. My personal, non-professional opinion is that you should definitely talk with someone about both of these losses and what you're now experiencing. However my thinking is that talking with a counselor or mental health therapist would be the better way to go rather than to try talking with family and friends.

My own personal experience, with these types of situations, has been that while family and friends may be well-meaning, they really don't know what to say or how to provide appropriate support, and besides they have their own problems and concerns. So they're not really interested in hearing about someone else's. Of course, if you have a family member or friend you feel will be willing to take the time to listen and provide support, certainly talking with them may be fine. As I wrote, above, I do think it's important to talk to someone. My best wishes to you.
