Jaundice?

21y/o Female 5ft 4in 215lbs non smoker, no issues, no meds

I am 4 months postpartum and everything is really really feeling sick and uncomfortable. I am an exclusively pumping mom 4 months postpartum. Since giving birth I have lost about 40lbs and have an extremely hard time eating (1,000 calories a day)... My whole entire body severely aches. I've been constantly weak. I cannot consume ANY cows milk products due to baby having a severe CMPA so eating is extremely uncomfortable and anxiety ridden for me. I do take a calcium+vitD supplement due to this. My skin is bruised in several places including my arms, legs, ankles, feet, and a few little ones on my abdomen with no clear explanation and my muscles hurt and feel like they're constantly flexed. The reason I think maybe jaundice is because to me I think my skin is looking a more yellow tint than normal but no one else thinks so. I just wish I had some answers. I feel so exhausted and can't sleep more than a couple hours at night or I wake up with pains in my [ ribs? ] and arms.

I'll post pics of my skin and eyes below.
