I am stuck ,what would you do in my situation?

hello everyone

So I am a freelancer on fiverr since 2020. I work on Amazon related services and since then I have made around $300k.

it was going well until 2024 but after that fiverr went bad and since then I am struggling quite a lot.

now I barely get any clients and the biggest mistake I made was that I only depended on fiverr.

Now I can see that 98% of my old clients have actually left the platform and my orders are 0 when I'm top rated.

so what should I do in this situation? please guide me.
