ANOTHER pregnant friend and I'm bitter and sad

Found out on Friday that yet another good friend of mine is preg with her 2nd and they got preg first month trying. When she told me I burst out crying and I know she felt bad but I can't help it. I feel like I'm losing all my friends cuz they are all pregnant or have kids and I am distancing myself from them since it makes me so sad. I just can't handle being around so many pregnant women and babies I don't know what to do!
