Iron deficiency , bruising , guttate psorias

Hey i'm new here and just wanted to see if anyone had any advice/help for me

I've been quite healthy up untill now with only a few colds and stuff here and there but since about the end of October, i've been in and out of my doctor's non-stop and the reason I'm posting here is because I don't feel fulfilled with what they've told me and I'd like to see if anyone on here could help me out.
I go to the doctors in my college and two of them have treated me at various times, so I don't really think either of them know or care about everything thats going on.
So, i went into the dr about iron deficiency as i had had it the year before and thought it was returning, but i also complained about bruising which i thought was from the iron but she told me it was not related, i got blood tests done, and they returned with low iron, something to do with my vitamin K which she did not explain, wheater i'm too high or low. She also told me that two of my liver functions were down (i don't drink so one of them was not affected) so she just said, i should try get my iron up take tablets if i felt like it but it was not neccesary, and to come back in a month for more blood tests, in the month i didn't take iron tablets and when i went back she gave out to me, i explained she hadnt told me it was neccessary to take them so i was just eating more red meat, anyway, those results came back and my iron got better, but my liver had worsened, no mention of vitamins this time around thoughm she said she had sent off samples to get tested for a viral infection cause that could be what was causing my liver problems, this was sometime in November, near the end i think, and i have still not been called back to get my results on that. But in the meantime, i developed guttate psoriasis so i was back there, i didn't get much information about that either of the doctor just that i should put cream on it and if it didnt go away i could go back and get steroids.
So sorry about the rant here, but basically I'm wondering could tere be anything going on that the doctors are neglecting? Or am i just being too paranoid?

Just a bit of information on myself to add, I'm 18, female, i dont drink, don't smoke, don't drink tea or coffee and don't do any drugs, i try not take pain killers unless its really needed, i had jaundice as a baby, my bruises are all over my body and of various sizes and colours, some only last a few days but others will last 2 weeks.

Again sorry about the extremely long post, i look forward to hearing from you!
