Good advice or also just host your own instance will be a great way and its very simple to do that I feel anyone with some technical knowledge can do it by using Yunohost.
Buy a domain using namecheap or cloudfare.
Rent a VPS on Linode, Vultr , Digital Ocean or Hetzner
Install Yunohost from the official website and be sure to install Debian 11 and not Ubuntu thats the one recommended by Yunohost developers.
Once Yunohost is installed , set it up , add your domain , add a DNS record to point to the the server public IP.
Now just installed Lemmy app from the Yunohost app store and thats it now you have your own lemmy instance.
