My mom called me out of the blue tonight after not calling or texting me for months....I sat there silent and so did she because I didn't know what to say, but I'm sick of being the one to apologize for her BS ways....so I didn't say I'm sorry for her and I wont. And then I said I had to go. Simple as that. I don't have time for her stress anymore. That's about as nice as I could have been because inside I was ready to scream her head off for so many things..
