I thought I was already 18. I thought I turned 18 back in April. I’ve received documents now I’m 18 about my “recent” birthday. On the 22nd of January. (which would make me 8 months younger than I’ve been living as) I had something similar happen when I was 16 and needed to get my National Insurance number. I got a letter around Jan/Feb time about applying.

I’m so confused. I’m really creeped out. I’ve never seen my birth certificate. They have all of my siblings kept safe but whenever I need mine for something they say they don’t have it.

I jokingly told my father about how weird it was I was getting these letters about just turning 18 this month. And he got defensive and was saying I was crazy when I didn’t even confront him or say it in an accusatory way. My mother then came into the room and asked what we was talking about and my father was like “she’s saying her birthday was the 22nd”. I said I was just joking it’s just the letter made a mistake. But I’d never told him the letter said it was the 22nd.

But I’ve kept to myself that slip up.

I feel crazy right now. Why would they lie to me about my age? My first thought was maybe adoption or something but we’ve actually done a DNA test before for fun and they definitely are my parents.

I have no idea what to do about this situation. I’m freaking out.

Edit with more info I’ve given in comments (skip if you want)

I’m from the UK.My parents are also from the uk we aren’t originally from another country or anything so aren’t immigrants. They married in 2001.

So my known birthday is April 4th 2007. Some legal documents say that. Like my passport and provisional license. Some say January 22nd 2008.

The letters I received were one from my private healthcare service (not The NHS) saying I’m being moved to an adult service now.

One because I’m on disability benefits saying I have to change some info now. I also had a weird thing happen at a benifits appointment where they called me a minor when I wasn’t. And another one where I went to the hospital and they thought I was 17 until I corrected them I was 18. Also happened when I reported something to the police and they wanted to confirm I was 17 and I was 18. And they then were like oh yeah I see the correct date now and I gave my license as proof.

I am the oldest of my siblings. I have seen baby photos of me in the hospital. And heard my birth story I was born quite late apparently. Whereas my some of my siblings were born prematurely.

The second born child is 17 so we are very close in age.

There’s also a weird thing though I’ve noticed before but not overthought where on my parents old camera it had a date and time in the corner and I’ve noticed before that some of the dates where confusing. Like the second born sibling was apparently born in 2008 but theres newborn baby photos that say 2009 in the corner of him. His birthday is the 9th of November 2008.

And some that I appear younger developmental wise than I would’ve been.

I also did notice as a child hitting milestones later than my peers like there’s a video of me walking for the first time that says 2010 so I would’ve been 3? Which is quite late but I am disabled so I thought oh that makes sense but 2 I can see that more than 3. I also hit puberty slightly later than most of my peers they were like 11 and 12 and had their period and stuff and I was like 13 and I got made fun of at 12-13 for being flat chested. But since have developed normally since like 13. I just thought I was a late bloomer but now I’m questioning things.

As for why the DNA test was done. It was their idea to do the test for fun apparently because they’re obsessed with finding out ancestors and family history and stuff and it matches you to everyone who’s taken the test as well as people who’ve taken the test linking their known family members who have not taken the test. So we could see who we are related too and possibly find out more about our family tree.
