Do I have a right to be annoyed at my friend?

Sorry but I need to rant about something important.. So very long story short, my friend has been fucked up by her family (Adandoned by her dad for doing drugs, been threatened, mum threw something at her once) these are awful things that didn't deserve to happen to her. But I also have a difficult family, I've been emotional neglected and abused by them my whole life) my parents have never hugged or told me they loved me, they scream at my till their face had gone red and their spitting at me, my mum once screamed at me and threw my stuff down the stairs when she found out I self harmed. I feel unloved even to this day because of it. Then my friend found a pack of coke in her dads purse, obviously that's gonna crush her, and I was so sympathetic but then she came out with the comment 'like your family don't talk about **** and don't say they love each other but they don't threaten to kill each other'. First of all I thought it was mean to bring it up in the first place as it makes me upset thinking about it, second of all, it's is NEVER okay to compare your situations to others. These situations are so different. It's horrible to say things that suggest 'I'm worse if than you'. Mental health isn't a competition. I'm still mad about it but I haven't mentioned it her and it was yesterday. Dunno is I should bring it up or if I'm overreacting.
