Unable to find a comfortable bra that fits, extremely frustrated

I am having an extremely difficult time finding a bra that fits and is comfortable. I don't know if I just haven't found the right bra or have just become too accustomed to my old stretched out bras that anything fitting 'properly' is uncomfortable.

Recently purchased a bunch of bras from Bravissimo, even did a virtual fitting with them and discussed my measurements from this system. Only two of the bras even kinda fit (were unlined, which never seem to fit me well). The ones that did technically fit were so tight around my ribs, under my arms, and on my shoulders (even after adjusting the straps).

Here is how they looked (please excuse the spots from the dirty mirror...). I've included my 'favorite' bra, a Warners 36B that is at least 5 years old.

I've also tried and returned multiple bras through Amazon including:

I'm so frustrated and exhausted, especially seeing all the posts of people excited and happy with finding a good fit. What am I doing wrong?! Help!
