"i miss you" in Japanese not the lovely kind?

[sleepy]

Hello,

Going to see my old Japanese teacher on a field trip tomorrow and would like to say i miss you to her in Japaneses, however all the yahoo answers i've seen so far are for lovers or family and i am not quite sure how well that will go over :-).

The nearest one i found was "samishiku narune" - for missing you and "ouen-shiteruyo" - hope you are doing well.

However i do not know if these are polite and structured properly as she is a sensei and i would prefer not to make any mistakes that need to be corrected.

Thanks in advance...
