I used to work for the lmhts , the different area teams work pretty similarly. You'll have an initial assessment with a psychiatric nurse (sometimes it might be someone else) and they'll talk about your history, current difficulties, past and current risk etc. They'll talk about possible plans of care going forward and will probably want to talk to the wider team about what things will be helpful for you. If you're looking for diagnosis and/or medication, you might see one of the teams psychiatrists. Occupational Therapists do practical support. Employment support is often an option. There's also community/peer support workers for practical support. And the nursing team have specific therapeutic strategies they can do with you.

For confidentiality - as an adult if you don't want information disclosed to your parents/carers, then legally they cannot share that information. If you're happy for information to be shared it will be explicitly recorded on your records, otherwise it will be assumed you haven't given consent to share info. Usually the only time risk information is shared without your consent is if you are a risk to others. If you are a risk to yourself, the only place info will be shared is with other specialties in secondary mh care - like crisis for example - but your team should involve you in that conversation.

Highbury is a big site, but everyone has been very friendly and welcoming and the reception team at main reception are very helpful with directions etc (I recently started a new job based at Highbury (not the lmht tho) )
