Do you know what type of therapy you are having and who with? I would imagine the first few sessions will be quite light and just about getting to know you, learning about how they work and their rules etc ( they usually tell you all the admin stuff etc).
If I tell you about my experience it may help. I met the lady, she told me about how she worked- when meet, where meet, number of sessions allocated, length of time (50 mins, how weird I thought but they see someone every hour and have a ten min gap so sensible!!), what type of treatment they offered - eg CBT etc. then asked me what I wanted out of it, any questions I had etc.
It is not a magic cure. It is about helping you work out things and depending in the type of talking therapy as to the outcome. It can help only of prepared to use it and make changes. It does not work if not prepared to use it and it is not a life long provision by the NHS so useful to think about what want out of it. It can help alongside medication, support services etc. if after a few sessions you do not click with the person it is worth telling them that. I once had some private counselling and really clicked with the lady but after lots of sessions had to accept she was not helping me, however nice the sessions were - but it was my money and it was not a good use of it sadly.
Hope tomorrow calmer. Do you have any other support people you can contact, as therapist often do not allow contact between sessions, so often people have a care co ordinator ( a Cpn, to or sw) they can contact between sessions.
The best advice I was given when I had my sessions was to be myself and do not pretend to be someone else as they can not treat what they see!!!
Hope you can cuddle up in bed and have nice drink, or read or distract on Internet or a game or something ( which is what I am doing!!!)
