You do not owe a hobby a career.
Something can be enjoyable without becoming a side business, a daily practice, or evidence that you are an interesting person. Start by removing the performance review. If the sketchbook still appeals, open it. If it does not, you are allowed to give the materials away. Returning and letting go are both useful ways to finish a chapter.
Make the first session almost absurdly small.
Put one brush, one sheet of paper, and a glass of water on the table. Draw the mug you are already using. Play the two guitar chords you remember. Set aside ten minutes rather than an entire ideal afternoon. The point of this session is to discover whether the activity still interests you, not to catch up on all the practice you missed.
Try parallel play.
Invite someone to bring their own unfinished thing. You sketch; they mend a shirt. Spend the first few minutes deciding what you will each attempt, then work side by side without needing to entertain each other. Finish by showing one small thing you made or learned. Online works too: agree a short call and keep everyone’s expectations modest.
Leave an easy invitation for next time.
Before packing away, choose the smallest possible return: one sketch on Saturday, one chorus after dinner, one more wonky cup. Put the materials somewhere practical. If company would help, register an interest in making something with a Fellow Almost. It is an expression of interest, so there is no booking or commitment at this stage.
