Hi, I used this website a lot when I started learning japanese : https://realkana.com/ It was really efficient for me but it depends on the ppl. I was learning "line by line", for example first line : A, I, U, E, O Step 1, I select the line and study it on the website and write every kana that pop (You can find the stroke order here : https://en.wikipedia.org/wiki/Hiragana#/media/File:Table_hiragana.svg) Step 2, when I feel like I can remember quickly enough how to read I try to only write it. So, I write A I U E O on a paper and try to remember how to write the kana, I will repeat until I remember. Step 3, I add a second line : ka, ki, ku, ke, ko + a, i, u, e, o. It's important to keep the one you already learned so you're making sure you will not forget them. etc...... I learned kana in 1 week with this technic ! It's important to find which way to learn is better for you because after kana, you will have to learn kanji aswell so it's good to know how to start. Hope my answer is clear enough and helpful.

Hello, Sorry, I'm not a native Japanese speaker, just an N2 level Japanese learner. lol I feel like your friend wants to say "maybe I was a nuisance for you" and that's the reason why you didn't answer to her. I don't not if "nuisance" is perfectly appropriate, but I guess you understand what I want to say. I'm really interest to see what a native speaker would answer. Since no one has answered yet I hope I helped you at least a little bit.
