Ok yeah, sorry I didn’t look for the word téměř but more about ‘přišel o’. I see now it’s because it’s past tense, but do I then don’t have to include ‘jsem’ if it’s ‘I lost’?
Yes, you do. You have to specify the first person using this auxiliary verb. In colloquial speech you can also say "já přišel" but that is not considered standard.
