My best friend of 7 years is my MOH. She has always been a high-strung person and I've never had an issue with that but in the last year she has had melt down after melt down after melt down. She hasn't worked one full week in the last year. She constantly goes to the doctor, gets notes, and her benefits company keeps paying her and she just sits at home. I have tried helping her in any way I can. She has been constantly ditching me for the last month now, which is just not her. She will make plans to go to a movie with me, then texts me last minute to say she is sad or having a bad day and won't leave the house. I have asked her if she is ok being the MOH and if she thinks it would be too much stress for her. She says she will be ok next year. I don't care if she doesn't plan a bridal shower or bachelorette party. I don't need to have those things. My worry is that on my wedding day she will not be there. I am truly heartbroken and do not know what to do. I would never replace her even if she ends up not being in the wedding. I just am lost... Any advice on how to handle this situation?
