How did you cope with your offers being rejected?

My fiancé and I are new to the process but obviously not naïve to how competitive the market is in our area. But I have such a hard time once we put an offer in- I get extremely anxious and try to not get my hopes up but ultimately do and then am extremely crushed when it doesn't go through. It makes me want to stop looking but I still continue to do so because we've wanted a house for so long. How did you cope?
