Could I have liver disease?

I'm 20, female, 140 lbs, active, and I have healthier eating habits the last few years than I've ever had in my life. For awhile, I've felt listless. It's been a year of nauseating migraines, constant indigestion, fatigue, and depression. I have no money, and I feel whiny when I talk about it, so I've avoiding seeing doctors about my problems. I've been trying to take care of myself with a well balanced diet, good sleep schedule, exercise, etc. but nothing seems to help. Despite my efforts, my health gets worse. More fatigue, headaches, indigestion. In April, my symptoms became unbearable so I visited an endocrinologist on suspicions of thyroid problems. After several test, my doctor found a liver abnormality, but because of crappy insurance and no money, that's all I know. This last week, my symptoms again became unbearable but more serious. My heart pounds so hard that it shakes my glasses and clothes, and my face and hands tingle when I move, even if I'm just shifting myself in bed. Every moment I feel like I'm bordering on sleep, but I have trouble actually sleeping. I often feel faint, and just now I fainted walking, although I was more like crawling, up a staircase and fell back down again. I've thought I might be gluten intolerant, then lactose intolerant, and now I'm everything-intolerant, seeing as anything I eat causes my stomach to be upset. I already owe several thousand dollars in medical bills, and I'll let myself get worse, or faint in public or something, before I get deeper in debt. I want some new ideas of home treatments that will at least make my life bearable until I can afford to get real treatment. So, good people of Yahoo Answers, you're my last resort.
