help me revise the resignation letter

background ：I was this year graduate and I was employed in an education consulting company. The problem is my boss didn't give me instructor but other newcomers have one. By the way, I worked as an internship here with the contract of 3 months but i don't want to waste my time.
This is a negotiation letter, and if negotiates well, I would like to be a full worker but if not, I would like to leave.


Dear___,

I want to thank you for your kindness in giving me the internship in at SINOELITE. Before coming here, I have the admiration admired not only to you but also the whole staff here. At the first sight of the office room, I was really impressed by its novel design which sends a sense of comfort. Of course, when I came here I am was really appreciative about your leadership style with maximum freedom. But it’s a pity that I did not receive much on the job training and assignment. I know, being a graduate, I have to learn many new stuff things like new working skills and social relationships. Anyway, It’s a big transformation for me and I am so glad that I am making progress step by step.
Considering the situation that every back-up has an education consultant, every time when they got together to discuss same student, I feel that I was isolated because I wasn’t involved. This kind of isolation hurts me much because I cannot could not find my value here. Since the end of my internship is approaching, I want to know your decision about regarding me and the next working plan. To be honest, I am afraid to send this letter to you because you are the one with power to raise someone or fire someone, but I wish it’s this to be an effective communication based on equality and trust.

Best regards,

Anna
