Lost dream house, having a hard time mentally

I just wanted to write out my feelings as I'm having a hard time mentally. Me and my partner found our dream home, we have been saving hard and starting bidding on a house in a really nice area, everything we wanted in a home we found it in this one. So we made a very solid financial plan, got a mortgage and started bidding. It went on for a couple of days but we were told it would wrap up over the weekend due to the current bid and estimated value of the home. Friday night we ended up being the higest bidder, the estate agent said the other bidder want to pause for tonight which was great, we could get some sleep and not look at our phones checking on the bidding. We wake up the next morning with the estate agent saying a bidder came in with a secret offer that was much higger and the seller accepeted. No contact for a competing offer, we eventually found the final price and it was lower that are max bid for the mortgage we were approved.

I felt so annoyed, we took part in the bidding, it was going smooth, we just increased the bid each time so we could stay on top. I then can't help look back, maybe we should of made a really high offer, or maybe we should of done this or that differently. This was our first house we have bidded on, so our family says there would be other houses, but I fear in the back on my head I will always compare and have this sinking feeling in my stomach I've lost out in life and there won't be that dream home there to build a furture together. I'm having a hard time mentally thinking about it, espcially since we have worked so hard to save as much as possible. At the same time, we both have our health and hope somthing pops up in the future. I just can't let go of the negative feelings, and it's affectlying my mental health.

Just being able to chat to someone in similar positions in the past would help. Thanks.
