IMO just tell her that she can find a therapist and ask for tips herself.

And no you aren't unreasonable, she's either completely clueless about how much time is going to be involved in asking your T....or she's the unreasonable one lol.

But yeah at best she's completely clueless about that. At least she's trying to figure out how to deal with the situation tho. So I dont think she's intentionally using you, either, yeah.

And it's OK for her to be sad, I wouldn't pathologise it. But yes she does need to see someone to get help in dealing with issues
