One Letter Writer Need Two More

[Alkulu]

Hi,

So I'm a grad looking to apply to masters. It has been almost four years since I have been in school, and I have worked other jobs to pay back loans and such in a different city than the one I went to school for. Problematically, I have kind of dropped out of contact with most of my references. I have one definitely, but I haven't heard back from the other two, as of yet. 

In addition, I used to be friends with one of my references on social media, but that is no longer the case. I am wondering what my options are, or what I should do?
