Getting married in a few weeks and I'm grinding my teeth at night, can't sleep, palpitations, worried I'm going to faint down the aisle etc I'm worrying about everything 

The planning process has been horrible because of family drama/COVID and selfish friends which has made it worse and I do feel very alone. My partner understands how I feel but he isn't an anxious person so he doesn't 100 percent get it. 

I want to try and look forward to it despite everything because I'm marrying the love of my life and I hate that I've started to see it as a day to get through rather than enjoy :(
