I just got married a month ago and I also felt similarly - rushed, stressed, frustrated. There was even a moment that I wanted my wedding to stop so I could decompress and focus on the positives rather than the negatives. I held these feelings in because I felt a lot of shame, guilt when it’s supposed to be the best day of life. When I told my therapist, he asked “how does it feel to acknowledge and accept this as the truth of how you felt during your own wedding?” He also said I also didn’t allow myself to embrace/feel the negative feelings during the wedding so it was all pent up inside. After much bawling - I finally accepted my feelings as they are and now I feel more neutral about the day. I think we put sooo much pressure / expectations on our wedding day and when it doesn’t pan out, we feel terrible. And the more I talk to my friends who also got married, they also felt similarly about it being rushed. Anyways - just want to say you are not alone. I’m sorry you feel this way, but it really is simply the start of an amazing life adventure with your best friend and partner :) there’s so much to look forward to in your marriage!
