Hope this will be of some help to you.
I had severe postpartum depression after giving birth to my son. Is it likely I will have it with my second child?
I was sexually abused as a child and now as my marriage is approaching, I am beginning to freak out. What should I do?
I think that you should meet with your Fiancé' more than once and talk about different things to get comfortable and then tell him about the past unfortunate experience as well as the level of your comfort in terms of getting intimate after marriage. If you don't feel comfortable doing it on your own, you may want to get help from a professional counselor who can facilitate meeting between both of you.
Nonetheless, I believe that it is necessary that "genie" is out before marriage so it doesn't cause any complications afterwards.
Sometimes, Antidepressant/Antianxiety medication could also be useful during the facilitation process.
Hope it will be of some help to you. I fully understand your situation and empathize with you and wish that I could help more than that.

There are ways to deal with it. Among them the foremost is to try to have your shift change if at all possible. if that is not possible then you need to see a doctor and get the full physical exam including your mental health and ask your doctor's opinion if you could be the good candidate who may benefit from taking stimulant medication to cope with night shift and taking Melatonin when you finish work so that biological clock can be Re-set as per your work requirements.
hope this will be helpful.
