I think I need new friends

So I’ve pretty much had the same group of friends since middle school. Now that we’re older with adult responsibilities we don’t talk or see each other as much. These days when I actually do see them I don’t enjoy their company. In my heart I feel like we’re growing apart, Idk if they feel the same. Am I wrong for feeling this way? These girls have been like sisters to me for 10+ years. Lately I don’t like being around them because they have grown to be extremely negative, literally when I’m around them I feel my energy being drained. I’m married with two young kids so I don’t have much of a social life, but I don’t wanna be friendless. Advice?
