Hi please help. Just had the most difficult attack. "Just had" it means " almost or only"? Please help

The sky was like a stubborn, low-hanging blanket of gray. Rain hammered down in a relentless cascade, but rain or shine, I had singing class. Entering the building, I noticed the undergoing construction – hammering, drilling, the chaos. Thankfully, my classroom was quite isolated and blessed with soundproofing to some extent. Or so I thought. Mid-song, a sound of breakage pierced the air. A rogue drill bit had punched through the plywood wall separating us from the construction zone! My teacher, bless her heart, leaped a good foot in the air, while, I wasn't sure why, I just had foreseen this. Before we could actually do anything, several construction workers surged through the door, apologies tumbling out like loose nails. But frankly, no way they could fix it in time to enable us to continue the class. Staring at clattered tools, plywood panels and that big cracking hole in the wall, I couldn't help but laugh. However, my class was interrupted midway, I will continue it next week.

Every year many _________ travel to India to visit its famous places.

I was planning to attend an online course for academic purpose but I didn’t find a suitable one, and I wasn’t sure that just 2months to four is enough to move my level to the next. So what I did? I intended to dedicate some time to many tasks, like half an hour for spoken English on“X”, two hours for listening on YouTube, two hours for reading a book. I’m crazy on reaching the proficiency point, I want to remember all words I’m receiving, I want to have no new word that I don’t hear it before just like my first language. Is that possible? And how long it takes? It’s possible, and take two years through three. I guess.

It must be Ghosts!! In this TV series, Alison, the sole heir to Barton Manor, unexpectedly acquired the ability to see ghosts by falling from the window and then had numerous amusing stories with those ghosts in Baton. Although the plots may be childish sometimes, its figures of flesh and blood as well as light and fun dialogues left a deep impression on me. Furthermore, I not only laughed out loud while watching this TV series, but I also promoted my English listening as well as speaking and had deep insights into some life philosophies it conveyed, for instance: -It's so easy to make assumptions about people and then you find you don't really know them at all. Half the time, we don't even know ourselves. I suppose that we all have our little secrets. -Time is there to be enjoyed, not killed. If you're doing it right, you don't even notice the time. -There are times when one must go against the grain, make one's own decisions rather than simply following orders. As far as I'm concerned, entertaining yet philosophical is the most fascinating point of this TV series!

What does “ the bottom is out of the tub” mean here ?

Today. I want to explore with you the difference between face-to-face classroom lessons and e-learning lessons on the internet. I've done both and there's a very real difference. And if you're someone who hasn't had an online lesson before or you're just not sure how they work, we're going to be looking at that today.

Sometimes, I don’t find a comprehensible meaning of a word in the dictionary. Look at this example: I just started throwing photos of my Friday fits! Is it colloquial? What means throwing photos here? And what means fits here?
