Any of those would work and are grammatically correct. "What's worse" sounds a bit odd to me, though. "What's even worse" might fit a bit better with the other two and what you're trying to convey.

That's perfect!

Daily Activities

I woke up late today. I woke up between 09:30a.m. and 10:00a.m. I would like to wake up earlier then that, but since I've been working from home, I don't have the commitment of waking up early.

After I had my breakfast, I worked until noon. At midday, I had lunch with my family like I always do.
In the afternoon, I came back to work and I've been searching for videos who could help me with my english learning. I've been trying to find videos of American people; videos made by natives to natives, so I can understand how they speak with each other.

I've been searching for these kinds of videos because I will try to imitate how they speak. I've been taking English lessons two times a week from teachers whom I found here on Italki, but I wish to speak and practice more then that. Thinking about that, I've made a search on google about "how can I practice my speaking alone?". Then I found a tip. They say it's a good practice to watch videos in English and try to imitate or interact with them.

So, that was a part of my day. How about yours?

Non-native Portuguese speaker situations we can learn from

I've just watched this awesome video, on the Small Advantages Youtube channel, about mistakes of a non-native Portuguese speaker. Link: https://www.youtube.com/watch?v=EdSnfouTTlE

I think sharing what I've seen will serve two purposes: help me practice English writing and teaching Portuguese non-natives speakers a bit about what not to do (in a funny way) when talking to brazilians.

Gavin Roy has been traveling across many cities in Brazil (is he still traveling? If so, "has been" is correct. If not, then "Gavin Roy traveled" is correct). He shares his experiences through his Youtube channel and talks about cultural differences, what he enjoys, finds weird, and so on.

One of his last videos that I saw was about some (in his words) "ridiculous mistakes" he'd made when learning Portuguese. I'll describe one of them:

When he arrived in São Paulo, he struggled to understand why cashiers greeted him with "Good morning/Good afternoon. CPF?" (in Portuguese, "Bom dia/Boa tarde. CPF?"). He thought this was a common addition when greeting, so he kept saying that for people he met, which provoked laughs (correct but "which made everyone laugh" is more natural).

What happens is that here, in various (many, some, etc) stores, people ask for a personal identification number (CPF stands for "Cadastro de Pessoa Física") when generating invoices (put it on the invoices). That enables us to retrieve, later, part of the taxes payed, since it helps the local government controlling/supervising tax payments. (well done!)

There are other amusing mistakes he did that everyone could learn from ("everyone could learn from" is colloquial. "from which everyone could learn" is grammatically better). I guess he had fun and learned a lot from doing it and sharing it with us.

The hurricane.

Today I witnessed a terrible hurricane. The wind was so strong and so fast, garbage was flying in the air and trees were falling. I was afraid that I might get hit by something. Everyone  ran to shelters and all cars were stopped. I hope nobody suffered.
