I Have Borderline Personality Disorder

I have just the "bestest friend" in the whole world. Now that she's engaged, she doesn't seem to care. I needed her over here to help hook up my tv and internet (had to take everything apart because of having to box it up for bed bugs). I didn't think I was asking for much, and I even texted her earlier saying to call before she comes over. Thanks. Now I think my router blew, I've already used 2G of my 5G limit, and the month doesn't end until the 13th. I knew I would lose her. She's walking into a ready-made family. She has other people now. She doesn't need me. Nobody needs me. Why bother?
