So this is the first day of Ramadan for us , not yesterday.

I was tired yesterday , and I couldn't help i just slept before even the sunset.
next thing I know I woke after like an hour after fajr time, I had slept for nearly 12 hours.

Now I haven't taken suhoor I haven't even made my niyyah , and I feel so dizzy because I haven't eaten for more than 15 hours and now I have to fast for maybe another 15 hours.

And i don't know if I'm allowed to not fast today , and then fast it back after Ramadan , because I didn't do my niyyah
