Are you supposed to be this stressed planning a wedding?

My fiance and i are getting married in september and to be honest it has been nothing but drama and stress. I lost my maid of honor because of the color i picked for her dress than out of anger she said some very mean hurtful things. Needless to say i will no longer allow her to be in my wedding let alone show up.I know this may be a bit extreme but she crossed a line. Than i set up the ceremony location and had everything set up just to get an email from the town clerk saying that they have double booked my wedding! I now have a non refundable wedding reception on the 10th and invitations made for that date at the time i was promised and they want me to change my date because of their mistake. I will lose about 1000 if i change my date and will have to reapply for the reception place and for the ceremony location let alone the invitations. His family is on board one day and off the next. Im just getting so flustered with this whole thing. I thought this was supposed to be my day? I guess im just looking for advice on what to do i just feel so angry and stressed.
