Hi and welcome, Alice. Stella's absolutely right, you're not the first and won't be the last person to go to your dr with concerns over mental health. A diary can be very effective but requires time and it's important you talk to your dr sooner rather than later so another tip is to simply note down all you've been feeling - mentally and physically - and take the list with you. Include everything. And do you have someone who can go with you for support?
