Could you try crocheting something for a purpose? Say, make small stuffed toys to donate to a local charity?

That way, the task becomes "meaningful" and thus worthy of the additional time and focus that it demands, without becoming a pressing obligation on you to cause additional stress...

I did have a purpose and it didn't help much in this regard, it only helped with keeping up the friendly pressure to actually finish them. But generally, your advice is good nonetheless.
