May sound selfish and possibly rediculous

So, because of our miscarriage, we've been told no sex for at least 4 weeks. I understand the reasons, but I find it completely unfair. I want and need to have sex with my husband. We didn't get to bring our son home with us, we've been grieving and I've been healing physically. I want to be close to him, in that way. We don't have a baby to wake us up all night and focus on. We have each other. I'm so frustrated (for lack of better word) and it only makes me more sad I cannot be that close with my husband- I need that comfort and closeness. Anybody else find this hard? And don't get me wrong, I'm not talking about sex as in I'm "horny," I'm honesty just craving that closeness and intimacy with him.
