Ayesha: I understand. I will write something that you might be able to work with to express your feelings. I understand that away from a group, you want to communicate your indebtedness to this teacher and mother figure.
"(teacher)" Words alone cannot express the deep bond that I feel for you.
You have guided me and cared for me and I will always remember your lessons.
Some of your lessons were general, but I always felt that some were deeply personal.
I hope that we can always be friends."---Ayesha
Remember Ayesha. Strong feelings can easily overwhelm us and if you try to say too many things all at once, you may not be able to keep your ideas from getting confused while speaking emotionally. So keep your message sweet and very short. About 3 sentences at most is what you need, and the shorter each sentence is, the better.
Let's have another example:
"(teacher)" I will always remember you as the one great light in my experience at school.
Were it not for you, my experience here would have only been ordinary. I hope you will be proud of your student."---Ayesha
