I am fucked, right? Me against the Home Office

[EuropeanBritInDespair]

Hello everyone,

I'm in a horrible situation. I have name changed for this.

I have dual citizenship. The first citizenship I acquired was when I was born in another European country. I also got British citizenship 18 years ago because one of my parents is British.
I have lived in the UK for many years.

Due to me having a British passport, I didn't apply for the EU settlement scheme.

Yesterday I received a letter from the Home Office informing me that I am an EU citizen and that I didn't apply for the EU settlement scheme. They told me that I have to apply within 28 days. Otherwise, I will lose all my rights in the Uk, among them my right to work and my right to receive free health care.
I tried to call them all day long on their hotline yesterday and todayto inform them about their mistake. I was kicked out of the hotline every time I called. Apparently, they are "too busy and there are no spaces left in the call queue". I even called first thing in the morning when they opened and I got this message. My partner also tried to call them and got this message.

I don't know what to do. I booked an appointment with an immigration lawyer next week to find out how I can defend myself and my rights.
I will also send a letter with recorded delivery tomorrow to their office with a copy of my British passport.

I'm honestly very terrified. I'm scared I will lose my job and be separated from my family.
On top of that, I'm almost 12 weeks pregnant and I'm worried I won't be able to access maternity appointments and give birth in a UK hospital anymore if I'm officially deemed illegal.
We also receive Tax-Free childcare and child benefit for our son. According to the letter, that will be stopped as well if I don't apply within 28 days.

I already see myself being arrested and detained for deportation.
I know I haven't done anything wrong, but I know my fate relies entirely on the fact if I'm able to get through and the goodwill of the home office employees.
The appointment with the immigration lawyer already cost me 150 pounds.
I'm feeling quite depressed and sad. I had a headache all day long and don't feel well.

Is there anything else I can do? I would be grateful for any advice x

I’m a dual British and Irish citizen. I had to supply my passport (currently have just an Irish one though did previously have a British one and was born in England) as proof of ID for my landlords. They recently threatened not to renew my tenancy as I hadn’t applied to the Resettlement Scheme (which I obviously don’t need to do). They told me then that lots of their Irish tenants had “voluntarily” applied to the scheme (blatant lie) when I challenged this. I think there’s a lot of confusion at the moment and it puts so much unnecessary stress on people. Please try not to worry, it sounds like a storm in a teacup xx

Sorry I meant settlement scheme not resettlement!

Crikey. I was expecting some sort of complex deportation case, not just a standard letter asking you to call them so that they can update their records!! I think that you need to stop panicking and calm down.

Stop, take a deep breath and stay still for a minute. You are a British citizen, send a letter and a copy of your passport. It will be fine.

Ok so I don’t know who is trying to scare you but you’ve been given incorrect scaremongering information.
It’s a simple admin error. You just need to tell them you have British citizenship and a British passport and that’s the end of the matter. I am talking from personal experience.
