Just an update: soe days ago I told something to my mum. I just told that sometimes I feel the desire to talk to a psychologist, without saying why and neither that I'd like to see one soon. I've been very generic. I took the idea here at PC She said that for her it would be fine. It went well. But now if I really want to go I'll have to touch the topic again, being a bit more specific. And I'll have to tell it also to my dad...this scares me more. I don't think that he'll find it as 'normal' as my mum, and I don't know if this time they'll easily accept that I don't tell them the reason. But at least I've done the first step.
Thanks for all te support I imagined that you would have liked to know.
