Need advice

So this is something that has had an impact on my depression over the years. My boobs never grew. I am 28 and there is just nipples pretty much. I’m 5’7 around 125 pounds.

I’ve worn padded bras as long as I could remember and I’m just so sick of it. But I’ve gave off the appearance of having decent size boobs to everyone pretty much. It even affects my sexy life though because I will not take my shirt off. It’s embarrassing to me. Is there anything I could do maybe? I have been pregnant twice and I went from super flat not even an A cup to 36 C very nice boobs 😭😭 why does my body hate me so much
