@sarahpanda - I am so sorry to hear that your husband has died, and that you are in such pain.
There will be some people you know who will say things that you will consider very insensitive in the days ahead. That's a given. Try not to let those comments hurt you-- let them roll right off of you. Grieve as deeply and as long as you need to. Every single person going through the loss of their beloved spouse has their own timeline, their own grief journey, to experience. You, and only you, are the captain of that ship.
I wish you all the support you need from family, friends, and any outside groups you decide to join. Reading about the experiences of others with circumstances that are similar to yours might help you. Writing about your love for your husband and your happy memories of him, and even your feelings of despair, in a journal might also help you feel reconnected to him. You do you. Take all the time you need to grieve, and do not feel guilty about doing this. You are entitled to your feelings at every single moment.
Wishing you the very best at this moment, and into the future.
