How crazy am I for having quit my job?

So I’m 25, I graduated university in September 2024, travelled and got an internship in public affairs July 2025, have worked since then, finishing up my internship after 6 months and being in my new role, which I’ve now quit, for coming up to 10 months - my final day will be in 3 weeks time.

I was a run up on the ladder, so entry but needing experience and have done a good solid job, but have quit as the firm was not for me, the company was small (10 people) so no HR or structure and the work load incredibly intense and overwhelming.

Whilst I am happy with my choice, I’m also now at a crossroad of thinking - have I fucked it for myself in the long run?, and is my decision going to be counterproductive.

But I also know on the other side of the coin I have nearly 15 months solid experience and could travel, being only 25?

Serious call for help - how should I feel?

To note i do not have a back up yet but I have savings to support myself
