Does this sentence make any sense? Is it grammatically correct?
"I would like to bear this stressful time on my own".
Is there any other polite way to say that it is stressful time for me and I appreciate their help but I would prefer to be left alone?

Answer

I would say: 
I deeply appreciate your concern, however I am doing well.

Good job 👏

Answer

You could say "Thank you for your offer to help but I would like to deal with this stress on my own". Alternatively, you could also say, "Thank you for your help but I handle stress best on my own".

Answer

The sentece it's correct but I believe you answered you own question later on when you said:  These are stressful times for me, and I appreciate your help a lot but I would prefer to be left alone for now"
