Those are three completely different "hates".

Women's butts often do look like a deflated upside down heart - it is a very apt description - so you are describing a common reality. So you "hate" something that commonly is a part of a female's appearance.

Then, you hate your shoulders and hands because they look manly. So here your "hate" is about not fitting a stereotype.

Then you hate your boobs because they are too big. So you "hate" having a lot of a body characteristic of a female.

Finally, you hate how your boobs do not fit in a bra. This is actually an easily solvable problem - if you get professionally fitted by a bra fitter at Nordstrom or one of the specialty lingerie stores, you would get bra that would house your boobs just right. You would need to change the bras every 6 months, though, and care for them properly, never putting them in the dryer, washing them on delicate and drying them on hangers in the position that the bras would have on your body. It is a lot of expense, both in terms of money and time, but as they say a problem is not a problem when it is solvable by throwing money on it - it is just an item of expenditure.

The three "hates" that are not items of expenditure but actual problems are distinct: 1) hate normal female body look 2) hate not having feminine features such as narrow shoulders or little hands 3) hate having too much of a feminine feature.

One can say that problem (3) might go away on its own if you start wearing expensive, well-engineered bras.

So down to problems (1) and (2) - and this gets really complicated, because they are in direct contradiction with one another - if (1) is true, then you should welcome having manly features, but that contradicts (2).

You are a very complex individual with a lot of internal torment and internal conflict. Hopefully your music career will benefit a lot from that level of complexity inside you, so there is a silver lining.
