Yeah .. You need to take care of you. Your treating your depression and doing Therapy, and that is what must be done. You have a life full of issues to wade through ( same here so I understand)
I hope you can take the time you need to heal and find out if this marriage is what you want and need.
The "honeymoon" phase in a relationship is fantastic ! But that does fade and thats when you can really see a life with or without someone.
Take care of you
