Yes, pretty much. I bought a domain to make sure I only have to do this once and parked it with Infomaniak.

Then I setup a new mail account (by now I abandoned Proton for Infomaniak there as well)

The next year I just kept responding with my new email address, asking people to update their contact data and each time I logged in somewhere I changed my email address. This went really well, just 1 or 2 services where I couldn't change it because they only accept the big providers, no custom domains.

In the end the first 3 weeks were really painful, afterwards it was smooth sailing.

Since then I've swiched provider quite a bit from Proton to Zoho and now to Infomaniak (where I will stay for a long time I think) and each of those changes took me about 2h each time.

So in sumnary, you will curse yourself for a few weeks and thank yourself later!
