i have a CAMHS appointment tomorrow...

with my new therapist Emma.. I'm REALLY anxious as its only going to be my second meeting with her and im not sure how she works yet :S im really anxious.. i guess i should tell her about my suicidal thoughts..but i dont know..a few people i know have said i should be put into hospital, but im scared of that happening.. i dont want to go and im scared if im honest with Emma then that will happen. im scared of telling her how i truly feel incase  i get locked up. I DONT KNOW WHAT TO DO.
