angry at my mum! - she always wants the attention

♡ 𝓚𝓪𝓽𝓻𝓲𝓷𝓪 𝓵𝓸𝓾𝓲𝓼𝓮 ♡
So my mum isn't normal she basically had an undiagnosed mental condition, one of which is definitely bipolar but she has more going on than that.
After a rough upbringing of her stealing money from me and my sisters and arguing when drunk every night and wishing death on us, plus trashed our rooms. Banned us from seeing our friends, lied to us and sometimes hit us. Etc. 
I am a single mum after my husband abused me and the reason i didn't see any major warning signs was because he was acting like my mum which I grew up to know. I left my husband for the safety of our baby as I know from experience that being brought up with a psycho can mess you up
My family are concerned about my wellbeing because being a single mum is hard. Financially I'm kinda stable but only just ! People ask about me and so my mum tried ( as per usual ) to make the situation about herself
THIS IS WHAT PEED ME OFF...
my sister spoke to her about me being alone and my mum said she knows how I feel cause she apparently raised me and my sisters single handedly (she didn't). 
She said that because my dad worked but he only had an office job! So my sister got annoyed and kept swaying the conversation off to get it back on me but my mum wouldn't let that happen
In the end my sister got so annoyed with her that she said " you don't understand what Katrina is going through, you didn't raise us on your own and the BIG difference here is..... atleast you knew you had dad coming home every night to see you". As you imagine , my mum didn't know how to respond to that
Am I right to be angry ? I mean, I am but man I need counselling this is why I kept having weak moments and messaging my abusive husband cause I've been raised thinking this is normal and of anyone in the world your mum should love and care for you the most right ? 
She took rent money off me for 3 yrs while she couldn't be bothered working, £600 a month! To live with my parents that's nearly £22,000 I spent !!! & did I get paid back? Heck no! They went out as they're alcoholics and got drunk with money they saved cause of stupid me and they'd come back and argue for no reason. 
Slam doors, steal our debit cards and cash. Trash our stuff. Bully us, make us have panic attacks. Scare our pets. Wish death on us.. everything like that
So to sum it up.
I always dreamt of having a man, like a saviour to ease my heartache which I already had by showing me love. I thought I'd found that. When I first met my husband he was the nicest most genuine guy you could meet, but he changed into my mum ... how could I be fallen victim TWICE ?!?
Is it me ?
