Do any of you regret having a DIY wedding?

My fiancé and I want to go as DIY as possible in order to save money. My fiancé is an organizer and has planned huge public events so they know how to get it done, but when I sit down and actually think about what needs to get done, I immediately get overwhelmed.

Do any of you regret going DIY from stress and wished you had had someone to do it all for you and if you don’t regret it, what are ways you overcame the stress and overwhelm?
