No I really don't think they would be angry- it's the exact place your supposed to tell people if you are at all concerned- if anyone were to react it would be with feeling worried and that can come out in various ways but angry? They don't have anything to be angry over- the only thing therapy requires is that you are honest- you get back what you give and if you hold it all back, your sessions run out and your left alone with your problems. If you share, you get a second pair of eyes and support with your problem and if they are doing their job right, you should be able to talk through ways you can cope when you are by yourself if there is no one to lean on. We all need someone and if there is anyone there, it's only going to bring you closer to say if you're struggling. Please try to say something- what is it your finding scary?
