Stop punishing me with the silent treatment! It is messing with me.

I am being affected badly by my ex friends refusal to speak to me. I cannot sleep at night. I barely get to catch up during the day. I am exhausted please stop this behaviour because it is affecting me in a negative way now. It is wrong to punish me the same way that your son continues to punish you. I apologised and it would be nice if you stop taking it out on me when your past actions got you into the mess with your son in the first place. This isn’t fair on me. I was only ever good toward you. If you really ever cared as a friend then you wouldn’t feel comfortable treating me this way.
