<human>: I'm going to try to make this as short as possible. I gave my friend a nickname that she really doesn't like, a couple of days ago I sent her picture referencing the name. She saw the picture and didn't reply, she never replies to messages so I didn't think anything of it, but later on I started having a feeling that I fucked up so I apologized to her and I called her a few times. She didn't reply or answer. So the next day I did the same thing, called and sent her an apology, no answer or reply. Yesterday I called her 3 times and again got no answer. I really don't know what to do, I've never gotten the silent treatment before so I have no idea how to handle this. Should I leave her be? Should I continue calling her? What should I do?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My asshole self sent something stupid to my friend, she's giving me the silent treatment because of it. What should I do?
