Please don't be offended by this. I'm just trying to help.
Just some advice, your comments would be a lot more understandable if you used some punctuation. Full stops and commas go a long way in helping us understand. Your grammar seems pretty ok. You just need to punctuate your sentences.
For Eg: Your sentence with punctuation would be :
Sorry, my bad. I am having health issue and will be leave site until my health is better. ~~and~~ you see I am take thing wrong and do apology ok and at time, focus or trying to make sense is hard for me. I have
Post-traumatic stress disorder (PTSD) and
Epileptic
Not perfect, but it is a lot better.
Also, best of luck for your health!
