Whats are Sam Houston thoughts about leaving the Union?

despondent

Explanation:

Sam Houston was feeling despondent  because he was leaving the Union, and the Union has helped him overcome many obstacles, and has helped him, and they kinda became like a family to him (well that's what my teacher said). So leaving that "family" makes him despondent  because it's like losing a part of himself. But even though he is leaving the Union, he is taking a big part of what the Union has helped him with, for the near future.

Hope this kinda helped!

Have a day!
