Yes, it makes sense to me that a streak can itself become a source of added pressure, and that you could think about it as you did, and then BP almost as an experiment if you will, to see if the thoughts would go away.
What did you find out: to what extent did the thoughts go away, at least for a time?
Was 14 days your longest streak ever, or in a long time?
I think that you are doing good work right now on BP,
, even though you had that slip. It sounds like it might be helpful to think about and/or speak to your therapist about how to deal with the pressure that may come again if you go a long time without BP.
