I am studying a bit of English as usual. I found that I haven’t written dairy the other day. I bought a pen and notes what I like for myself in order to good studying, but I forgot to write the dairy by the pen on it. I sometimes consider myself lazy, often asleep during the study.
And sometimes I am slowness most; sometimes I mean to try my best to be good but the result not so good. Okay, that’s fine. Maybe it is not so bad.
Not sure if this is good but please have a look at my version:
I study a bit of English as usual. I've found that I hadn’t written diary the other day. I bought a pen and a notebook I liked for myself in order to study well, but I again forgot to write the diary by hand. Maybe I'm just lazy? Occasionally find myself asleep during the study. And sometimes I am really slow. I try to do my best but the results are not so good. Okay, that’s fine. Maybe it is not so bad after all.

Hi, this is late but here's what I would write (as an English native). I'll give two different examples; one fixing the original statement and the other would be how some like me (a native) or someone else would probably say it in real life.
1. (Minor changes to the original) I'm studying English as usual. I haven’t written diary the other day. I bought some pens and notes that I liked, but I still forgot to write in my diary. I often consider myself lazy, usually sleeping instead of studying. Sometimes I'm really slow. I try to do my best but my results aren't that good. It's fine though.
2. (Edited, slightly different to what someone might normally say) I've been studying English, like always. However, I didn't write in my diary the other day. I got some stationary items that I like to help me study better, but I still forgot to write. I'm pretty lazy. Typically sleeping instead of studying. Sometimes I'm really slow but I try my best to get better but my results aren't improving. It's okay though.
And if you really wanted to just keep it short you could simply say: I've been studying English for a while but it's not improving. I bought some stuff to motivate me but I still didn't do anything. I'm just lazy and really slow but I still put my best foot forward! It's alright though, doesn't seem too bad.
I'd say that most people I know (including myself) would just say the third sentence, but either of them can work in daily life since they're fairly casual (although the first sentence is a bit more "formal" or something you'd see in text/writing than speaking).
