Anyway, I then left my bedroom toward the living room and I checked for if there awere any meals on the table to eat it, and. I found a little bit of roast eggs mixed with some olive oil and, cheese, and a piece of bread

I will describe how my day how it (went/was).

was is fine from a grammar point of view, went is more natural sounding though

Today uUnfortunately today I woke up lately at three o'clock exactly.

You need a subject for the first action "left" here, but you can then omit it from the second one because you've already introduced it by that point.

If you used "any" here you'd need to use plural "meals" and that would change a lot of of other grammar as a consequence. Instead I just changed it to "a meal" to rewrite less of your sentence.

I will describe my day how it was.

"Describe" means to tell me how your day was. You don't need to say both things.

Today, unfortunately, I woke up lately at three o'clock exactly.

The word "unfortunately" is an interruption in the sentence, so it should be enclosed in commas. "Lately" means recently, in the near past. "Late" means you didn't do something on time. The time when you woke up doesn't seem to be important since you don't describe anything that needed to be done soon.

I keptrelaxed until around half past three. Then I got up feeling ashamed of myself.¶
I relaxed until around half past three, and then I geot up with felling of shame onfeeling of myself.¶
I relaxed until around half past three; then I got up feeling of myself.

"kept relaxed" is not how English speakers talk or write. There are two different sentences here: "I relaxed until have past three" and "I got up feeling ashamed of myself." There are several way to correct this as I showed above. You can make two different sentences. You can add a conjunction such as "and," or you can join the two sentences with a semi-colon. "Then" is not a conjunction.

Anyway, then I left my bedroom and went toward the living room, and I checlooked for if there are any mealany food on the table to eat it, and I found a little bit of roast eggs mixed with some olive oil and cheese and a piece of bread

This is a rather long sentence. You might try breaking it up into two or three sentences.

I kept relaxed until around half past three then I geot up with fa feelling of shame on. (then I got up feeling ashamed of myself.)

Unsure of how to describe your meal exactly. Maybe "I found eggs cooked in olive oil with cheese and a piece of bread."
