Daily Answer Writing guidance

Hi everyone,
I gave my first prelims in 2018 when I was still in college. Qualified but it was mainly because I panicked and spent 5-6 months on prelims itself and a lot of questions came from my optional subject(history). After 2018 pre, I immediately went to Delhi and joined GS coaching( a mistake, I know) for 2019. 
Because of some health concerns I was unable to give prelims in 2019 but I am pretty sure that I would not have qualified this year. The same reason made me leave Delhi and I have been preparing from my hometown.

Now, for 2020 I am mostly done with my optional and GS 1,2,3. Essay and Ethics remain.
I am having trouble in answer writing for GS. There is no one to check the answers.
So my questions are:

1. Is there any online initiative( reasonably priced) for GS which can check my daily answers? I don't need a test series right now but only get my daily answers checked.
2. I have been following secure for answer writing. Is there any better alternative present? Both for quality of questions and peer review(insights peer review in comments looks more as an attempt not to upset people instead of genuine review)
3. Any guidance on how to approach essays would be appreciated. I am a total noob on this. Like any material or even a good video series(although I would like to avoid videos).
4. Lastly, and a bit unrelated, Is there any other platform where people are posting queries and having discussions? discuss is not what it used to be. people have left/inactive. Moreover, I have not been able to login there for the last one week atleast. quest has less people and was made for pre only.
