You do not have to make an excuse for any choice you make regarding attending church. God understands what you are going through. And going to church does not change your faith. Church is there so you can get a boost in your faith and have others to share your faith with. But just because you take a break doesn't mean anything.
You also do not have to tell C anything either. Letting him know that you are going through a rough time and need a break is good enough. He may want to know more but that is ok. You can respond in generalities if you need to. As long as you are kind yet firm about it, you are fine telling him nothing but that you don't want to talk about it.
It is fine that you don't want to be around people. Everyone needs time to recover and that sometimes means that you need time alone to think things through. And spending this time focused on yourself is a great way to heal. You will reach out if you need someone so it's not like you are isolating yourself.
Having Linda talk through therapy is ok, but you might not benefit at all and might as well not go. You may want to tell her that you don't have anything to talk about and see what she says. Or cancel all together if you feel rest would be more beneficial.
Okay. I'll see how I feel about going to my session in an hour or so, then maybe call to cancel. I'm usually the last appointment of the day, so it's not like it will waste her time. She can just end her day a little earlier. At this point, I might benefit more by getting work done, too.
You're right -- I don't owe C any info. he knows I need a break and generally why. I don't have a duty to share everything with him just because he listened to almost my whole stupid story, right?
You have no obligation to C at all. Just because you share your story and he helped you some does not make you in his debt to the point that you have to tell him every little detail if he wants to know. Plus you serve on the praise team, which helps him, right?
Let me know how your appointment goes with Linda.
