Losing motivation - job hunting

About a month ago, I started looking for a new job. The search was going well at first. In the first two weeks I had secured 3 interviews and was feeling very positive. As of now, one job ghosted me before even interviewing me, second job interviewed me - and while I thought I smashed it, still hasnt been in touch to arrange the final round. Third job seemed great, I was genuinely excited to potentially join that company and after two rounds, they told me that they have closed the position. While they are looking for a "team match" to bring me in, I have no hope it will lead to anything.

I appreciate I have only started looking a month ago, but I already feel drained, and I'm losing motivation. I'm in probably one of the few sectors that is no on its knees yet (development / construction), but I don't remember changing jobs being so draining. How do you wise people cope with it? Do I just need to chill out and enjoy the process?
