In google search console, there is an area where you see total indexed pages. If your pages have dropped off the google index, then that is the column you need to look at.
Firstly, please post here how many pages were indexed by google at least a week back. And then what are the total indexed pages 2 days ago (it wont show current days data)
If there is continous drop in indexed pages then there is a problem somewhere on your site or off your site due to which google has deindexed your site. I see that you have a lot of pages on your site. So i checked duplicate content. I copy pasted a certain piece of content on your site in google
There are many sites with the exact same wordings. I dont know how many pages are duplicate or plagiarised like this. I am also not accusing whether you have plagiarised or they have plagiarised from you. But it seems, duplicate content might be a major problem. So look into the same.
Your blog index says your blog has close to 800 posts. And it seem you are back in google index
