Am I wrong for this?

So basically the other day my mom had a meltdown on my brother. (he does drugs and she refuses to kick him out.) then once my brother starts fighting with someone, then everyone starts fighting. I was in my room and didn’t get involved, when my mom barges in my room with my friend there too & starts flipping out on me for no reason at all. Whenever I say no reason at all, I mean it. I don’t even know why she was so mad at me. Then she fought with my dad, told him she hated him and then left and hasn’t been home for 2 days. She does this sometimes and I honestly think it’s for attention. I know she is safe, my brother just talked to her on the phone yesterday, but I know she’s going to hold over my head that I didn’t call her and wasn’t worried about her. I think that’s what she wants. But if I try calling her, I feel as if she will try arguing with me some more so I haven’t. And also, I’m waiting for an apology that I will probably never get. I’m so tired of arguing with people and I have no energy to do so anymore. But, if I try texting her, she will be mad that I didn’t call. She’s very dramatic but I care about her. What should I do? Is it wrong to just wait it out until she comes home?
