I think I wrote 本当きで because I was at first writing a sentence using 本当に but then I decided to use 本気で so it was more like a "typo" hehe. So for the rest it was all because of my poor grammar.

In this phrase particulary:
まだ、私の日本語はひどいのであなたを理解する必要があります
what I was trying to say here was, that since my japanese is not good yet I need everybody's comprehension. I know it sounds weird and yeah, I knew it when I first wrote it and I don't know well how to express that yet.

I think that being this my fourth month on self teaching japanese I should be really better than this. And what is more, I've noted while writing this that my english is just... not good either hehe

I hope to improve soon and be able to express many ideas in good japanese.
