Most of those feelings are slightly dramatic, but for Noah it was FACT. Literally the Bible says he was the only one who was righteous. THE ONLY ONE ON THE FACE OF THE EARTH. That's slightly overwhelming, for anyone. Here's what it says about what was going on on the Earth around Noah.
"The Lord saw that the wickedness of man was great in the earth, and that every intention of the thoughts of his heart was only evil continually."Genesis 6.5 ESV
That's rough. People's hearts were evil, all the time. And we find out in v.11 that they were also, violent and corrupt. Not a pretty picture. So God is "grieved" (v.6) that he made people. The sad part is, remember back to Genesis 1 and how all of God's creation was GOOD? In just five short chapters his noble creation, created in his own image has fallen to this. You can hear God's heart breaking as he tells Noah that he will "destroy them with the Earth" (v.13). And yet the one bit of shining hope in this masterpiece of catastrophe is, "[the] righteous man, blameless in his generation, [who] walked with God," (v.9), Noah. And here, we see the foreshadowing of another man who was the only one blameless, righteous, and walked with God--Jesus.
Most of us know the story, about how God tells Noah to build an ark out of gopher wood and then to take two of every sort of animal on the ark along with his family to save them from the flood. He does it, and they are saved through the 40 days of rain and 150 days on the ark following the flood.
WHERE IS JESUS IN THE OLD TESTAMENT?

GOD VINDICATES OBEDIENT FAITH
Both Noah and Jesus looked like idiots while they were waiting for God to work. Noah waited roughly 100 years as he built the ark, waiting for God's flood. I bet he felt foolish at times, and when he didn't, I'm sure other people around were happy help him get there. But still he completed the ark, faithfully. And 40 days into the Stormageddon, his previous 100 years was vindicated.
Jesus, the amazing rabbi who healed the sick and fed the hungry, who rode into Jerusalem to the chants of "Hosanna" like a conquering King-General, was reduced to death like a common criminal. He was beaten, spit upon, shamed, dishonored, and crucified by the very people he was dying to save. On that good Friday, it appeared as though Jesus was not favored by God, but was in fact under his curse like the Pharisees and Teachers of the Law had said. His followers put their head in their hands and wept, "The Pharisees were right, all along." But three days later when he rose from the dead, God proved that Jesus was not under any curse, but he was favored above all people. That even death couldn't hold him. Because God vindicates righteous obedience.
