Soon to be married.. Not short of anxiety!

Long story short I used to be able to better manage my anxiety but last year I had a major panic attack which has caused me to have anxious fits ruminating about the future with my soon to be husband. Despite my "going crazy" he decided he wanted to marry me anyway and has been so supportive through everything. We were going to wait until later of 2022 but, you know, marriage can make a financial situation a lot easier haha (plus honeymoons are extremely discounted due to covid this year!). So now we are getting married in a month and a half and the honeymoon is two and a half months away.. I love this man, he's my support system and my best friend, but now that it's all becoming real and we are no longer just talking about it I'm freaking outt. Seeing my last name changing.. thinking about how we are months away from potentially conceiving our first child together.. just has me panicked. I have always hated change. Change is my biggest struggle next to the unknown. And this is just a lot of change coming fast with a lot of unknowns to ruminate over.. sos.
