Love your Qs. Cheers

is it something they can handle? Absolutely.
does it concern them? I don't think so and if it does he's good at not letting me know that or it could be my wishful thinking...
do they suggest medication is the only solution? Never.
do they want to find out what causes the thoughts? Yes. He's pretty adamant about that
do they show understanding? I got mad when he'd tried so not anymore
have they helped at all? Surprisingly yes.
if so, what have they done to help? By acting calm, asking why, how I feel ect. plus I'm pretty sure there's some kind of magic on his part involved.
do they want you to tell them if you have si thoughts? He never told me directly- I think it's implied in: talk about what's running through your head.
do they want you to tell them if you have si'd? The same applies here.
do they suggest hospital for si'ing? Never- hospital's just not an option for me and he knows that.
does it make them uncomfortable to talk about this? No- I'm the uncomfortable one.
do you feel safe sharing with them? Yes, I know he can take it and won't use it against me.
do you tell them the truth if they are able to hear it? Yep- otherwise, what would be the point of therapy?
do they criticise you for it? I would be out of the door and never coming back if he did. It's not his place to criticize any type of my behavior.
