How to find distribution function of given data?

I have some data(insufficient data, I mean I have just few data) that I want to find the best distribution function which can describe my data but I just don't know how to do it when data distribution seems to be so complex! any help there on this? thanks in advance :))

The obvious question is: how many data are a ‘few’? What are the mean, median, and std (standard deviation) of your data?
