This excerpt can seem difficult to interpret, but it's easiest to take it line by line. It basically means that the writer and his people have faced many hardships (obstacles) and have asked for change and help very humbly. The writer and his people continue to ask for help, but it only gets worse. Then, the writer compares the Prince to a tyrant (an unjust and harsh ruler), and says he should not be in charge of a group of free people. This is in reference to King George III, who was the oppressive King of England when this document (The Declaration of Independence) was written. Hope this helps!!
