Don’t go back to the old you just because the new you is lonely for a while.

Changing often costs you company before it gains you any. The old crowd fits the old version, and the people who match the new one have not arrived yet, so there is a stretch in between that is genuinely quiet. Loneliness in that gap is not a sign you made a mistake. It is the cost of the transition, and it passes.

Name the gap for what it is so it stops feeling like evidence. Put yourself somewhere the new interest is practiced, even once a week, where meeting people is a side effect. Keep one old friendship going that does not require the old behavior.
