Here's the context.
We had been dating for more than a year until we broke up a month ago. I' okay now.
However, the very first few days that I spent alone without her, it (seemed / was) like something I could never overcome.
However, the very first few days that I spent alone without her, it seemed almost impossible to get over her and become (well off / okay / good)
Q1. which one is natural among the words in the bracket.
Q2. in the #1, I tried to make 'it' and 'the very fist few days' equal, whereas In the #2, 'it' represents 'to get over~~',did I do well?
Q3. Here we can not remove 'the' from 'the very first few days' because it's definite time, right?
