how to get into SaaS sales or let that dream go?

i’m currently a b2b marketplace sales AE (full sales cycle) at a big name company. i really enjoyed it until the start of this year when the company increased targets by 20% the same time i earned a promotion so my total quota went up by 40% and i completely burnt out. i’ve been tryin to get into SaaS sales and have gotten a lot of interviews but because my current role is SMB and fast/less strategic sales cycle, no recruiter moves me ahead- some have sent similar feedback too.
staying at my current role is not an option. and the only offers i’m getting are similar sales or SMB account management. should i spare myself the torture and move to account management? how hard will it be to move to SaaS sales from that?
