Resentful after miscarriage!

So I just went through a miscarriage and it was one of the hardest things of my life because this pregnancy was so wanted! I’m now starting to feel resentful towards my friends and family that are pregnant! My boyfriends sister just found out she was pregnant and I couldn’t help but feel mad I wish nothing but the best for them but I’m so mad that she is pregnant and I am not I don’t know how to get over this feeling I don’t want to be around any of my pregnant friends because it makes me miserable! Has anyone ever been through this that can reassure me I’m not crazy for feeling this way😭
