I told my GP and told him how I was feeling who then diagnosed depression and we went down the medication route. I've had several referrals to secondary mental health services, hundreds of hours of counselling and tried various medications. It's not a quick fix and it's not one size fits all unfortunately, but if you have a GP who has an interest in MH they can be worth their weight in gold. I have severe clinical depression, severe anxiety and social anxiety, and it was my last referral and seeing a specialist nurse that got me the treatment I needed.
