Answer:
Dear Mr/Ms. Blank,
The amount of effort you've put in as a teacher is deserving of more than a mere "thank you." Despite the fact that the pandemic has taken a toll on our education, you have always worked tirelessly to provide us with the best educational experience possible. We are all grateful for your genuineness.
Best Wishes,

You can use the fourth verse. below is an interpretation of the verse.
when we are divided or separated
we sorrow or we hurt
we shall be joined in heart(maybe not physically but the person that passes forever holds a special place in someone's heart.)
but hope to see each other again.
The hatchet itself probably represents survival
And idea or meaning that is unclear.
( hope this helps! <3 )
