Today

I have a cold and a bad cough. Yesterday, when I came back home(1) from my job work(2), I took some(3) medication and I(4)went to bed. Today it isn't any(5) better, but I have to be at go to(6) work. Today I should go to a doctor. I hope that your day is better than mine.I wish you this.(7)

1. In English, you say "come/go home", not "came back". You can onyl say "came back" if you add the time you came back, for example "when I came back that night". But, to say "I came back", it can also only really be used if there is someone waiting at home and you told them you'd be back later.

2. We say work, isn't of "my job".

3. If you add "some" in here, it sounds more natural, because you didn't take a whole bottle of medicine, only a bit of it.

4. You have already said "I" earlier in this sentence, so there is not need to repeat it.

5. You need to add "it" in here to show that you're talking about your cough/cold. Without the "it", it looks like you are talking about the weather or what you have t do today. Also, if you add "any" in, it sounds more natural and show that it is exactly the same as it was yesterday. If you just say "it isn't better", that could mean that it is a bit better, but not completely better.

6. Again, you can only "be at work" if you say when you have to be there, for example "be at work today". If you don't want to say that, then you can say "go to work".

7. This sentence doesn't make much much sense. You could instead say "I hope it is." because you are talking about the reader's days.

I hope you get better soon.
