Waiting game

So my paper work was mailed on June 5 , I called to check on the status and was told that because it is an apppeal the insurance company has 90 days to review my case . They did say it prob won't take that long as it is being processed at this time . Has anyone else had this long of a waiting game ? Or has anyone dealt with bcbs of Ala ? I feel like my life is on hold , I am so anxious I can't help but to worry / think about it all day !
