I felt similarly before, my take is to gradually add social structure to life. direction can funnel and catalyse energy.

e.g. pottery, crossfit, book club. for me, it was bjj, a world of warcraft group, and a "beer club".

regularly watching and chatting in a small twitch stream could be a start, but beware its parasocial nature

solo activities add structure but social bonds reinforce discipline and motivation. "someone will notice my absence".
