how to explain gaps on resume

I do have some gaps on my resume. Nothing too concerning, but as time passes the more I worry about them despite people I'm working with telling me not to worry. I also have my resume some seasonal work and I feel like some employers may have taken it the wrong way and I explain that it was a seasonal position. I feel like telling them the truth and saying "It's not my fault I've been out of work longer than expected" or "My resume is what it is, you know how hard it is out there?" I feel like I have myself to blame for how I've been going about it, either way I need to do things differently moving forward
