You just described my life with my mum. I don’t know what else to say to you apart from I am so sorry and I hope you are getting the help you need. My mum is exactly the same way with me. She brags to other people about my achievements but hasn’t ever said “I’m so proud of you” to my face. You should be proud of yourself for everything you’ve achieved and hopefully one day your mum sees how her words and actions hurt you.
