If your GP surgery is like mine, there is more than one Doctor and some are nice and some are not so nice.
Sounds like you have experienced the bad ones.
Its hard to stand up to them when you are feeling anxious.
But, you can say when you book an appointment that you do not want to be seen by that one you found unhelpful. You dont have to make a complaint or explain why, you can just insist on seeing a different Doctor this time.
Alternatively, I think you can phone that 111 number and talk to someone on that number, tell them you have been having thoughts about wanting to die. They are trained to take calls like that and to take the caller seriously and help the caller to get the help they need.
Or have a look here to see if theres any other NHS help near where you live.
www.nhs.uk
And there is this -
https://hubofhope.co.uk/ - you put in your postcode and it will give you a list of places close to you who can help you.
It includes charities like 'MIND' who are all geared up to help you.
Maybe try these places if you can't face making a Doctor's appointment just yet.
Your tiredness comes because you are trying to fight the anxiety etc, so you are tiring yourself out and the depression/anxiety makes you tired anyway. So it's a double battle for you.
Please don't let one bad Doctor put you off getting some help.
For every
crappy health service worker, there are three good ones. You just have to try and stay strong enough until you find the perfect one to help you.
And ok, you havent had a full on shower/getting dressed/doing hair and make up etc every day - thats ok. You've kept yourself clean - which was a major effort for you to do - but you did it - so thats a huge 'well done' for you.
It may seem like a little thing to many people, but when you are suffering from anxiety/depression those 'little things' seem like huge mountains and we need to deal with them a little bit at a time.
You are doing great.
Posting in here is a huge step, too.
