So much stress and no help

I know that my little situation will not apply to a lot of people possibly reading this so I don't know how much anyone can help, but really just a listening ear and a cyber hug would be nice right now if nothing else. But here it goes.

I met the man of my dreams last year. After many breakups, anxiety attacks, and hardships these past few years I finally finished college, got engaged, and turned 20 this year. My life has straightened out considerably. I could not be any more blessed with a supportive, loving man. But now we are down to business with planning a wedding in August. My little phase of happiness has quickly vanished with the intense stress of being trapped in an awful job and unable to find a new one in my field of study. My second area of stress is the idea of my perfect little wedding that I have always had in my head, that is now falling apart. I have an extremely unwilling bridal party that I am praying even shows up and does their part. No true girlfriends to be happy for me in this chapter of my life and help with the wedding. And now my fiancs job is possibly changing in the next few months where he might have to work on our wedding night, cutting our wedding short and ruining any plans of a honeymoon. That last part has me in pieces.

I know there are people on this site with much worse problems than me, and I am grateful that my problems now seem small in comparison to how bad my life used to be. But I am going on day 4 of crying my eyes out from all of the stress that I feel. I just feel like a failure because I can't control my job or wedding situation. With no friends to share things with and my fianc working 10 hours every day on 3rd shift, I just feel stressed out to the max and isolated. If anyone has read this far then thank you wether or not I get any replies. I'm clinging to hope that some things will just work themselves out.
