please, correct this phrase ?
there are the times where we feel it's the end, then we discover it's the start, and there are the doors where we feel it' shut, then we discover it's the real gateway

Question

Answer

As Peachey said- capitalise it, and check the punctuation.
I think it would be better as two sentences.
You should take out the first 'the's (of each phrase) - 'times' and 'doors' are not specific.
And as I said - 'feel' does not really go with 'shut'. You can see if a door is shut or not. Have a think about other analogies that might fit?

Answer

e.g. your analogy suggests using 'feel' a door is shut, but that doesn't really make sense. The more obvious word is 'think'.

Answer

Corrections-wise, Peachey is correct. 
Mostly it is fine other than that. But there are a few odd word choices - which are more personal preference.

Answer

Check the punctuation and capital letters. These are important.
