I am sorry you are having to feel the depth of these profound losses. The best course of action is to find a group nearby that offers grief counseling. Grieving groups will offer support and a process for grieving, which you will be able to use for both the loss of your godson and your boyfriend. This type of grieving is layered and complex. A grieving group will give you a place to begin to sort it through and get you to to a place you can start to feel okay again.
Wishing you patience and peace,
