formula

...I'm struggling with feeding my daughter.. I feel like I'm not producing enough. she seems to still eat every hour and half to two hours. she's 10 weeks old so a little over 2 months. she's always fussy after I feed her and she cries a little during. sometimes is really hard to get her to latch too. my nipples are really tiny and starting to feel soft. I don't feel my boobs being full or empty anymore.. actually I just feel empty. I haven't been leaking like I used to either.. i did actually leak yesterday once. I didn't wear a bra all day just to see if anything would happen and I only leak because I was feeding her on one breast and the other dripped a little(my good boob).. I'm just not sure I'm satisfying her needs and I'm scared I'm not feeding her enough.. I've tried. she cries trying to latch. she cries after I finally do feed her.. it's soo hard for me mentally to give her formula... I just want to be able to feed her😭 --------------------------------update: her wet and dirty diapers are hard to determine since I do give her an ounce of formula if she's just NOT settling after being fed... also I don't feel the "let down" anymore..
