Can’t shake this feeling 😭

My boyfriend and I talked and decided we could start trying for our first baby. I’m going on 24 and can’t shake the feeling of being a “fuck up”. I have a great job, my own place, a car and everything but my mother was always a fuck up. She started having children at 14 and was always into drugs so I feel like a child that shouldn’t have a baby because I’m going to be judged by my whole family. They judge me for all of my mothers mistakes and treat me like I’m 15. This is something I really want and feel so ready for. I just wish I wasn’t embarrassed about it but I just am. I wish I could happily tell them we’re trying for a baby. Once I do get pregnant I feel like I have to pretend it was an “oopsie” around them and not that it was planned or else they’ll get mad 🤦🏻‍♀️ any advice for me? Anyone else ever felt this way?
