"realized" is a correct word for the context
may be or I came to the conclusion
well, I think you meant "I've come to the conclusion".
Because "I've come.." means you still think so
I don't think so,I'm tired and I don't think at all
better to use "present continuous" here not "present simple"
кому better пусть тот и use
