Kidney Disease after aspirin overdose? Please Help

So, I've been experiencing symptoms that I think may be either a UTI, or some sort of kidney infection/disease.

A bit of background:
Female, 19 years old, I haven't felt truly healthy in years. A few months ago, I was drunk and stupid and made a valliant effort to kill myself by overdose. I took around 75 aspirin (kinda just the regular size round ones). I waited about 5 hours before I got to the hospital. I only ended up going because the pain in my abdomen was absolutely unbearable. It was as if someone had taken a chainsaw to my insides. I had the most pain in my stomach, and what I was told were my poor kidneys. By the time I got to the hospital, nobody was very confident that my organs wouldn't shut down, and there wasn't a lot they could do besides give me around 6 cups of charcoal goop and hope for the best. ER dr's and nurses felt that it might be too late, until I started to stabilize.

I was told of the possibility of needing dialysis...but I'm a broke and stupid kid who does not have and cannot afford healthcare, and I was never able to follow up.

I guess I could also mention that this was a second attempt. The first being at the age of 13, taking about 40 aspirin and not seeking medical treatment.

So, I know that I have some degree of kidney damage.

Recently, I've been experiencing:
-Back/abdomen pain, in the middle of my torso, on both sides, and towards my back.
-Extreme fatique. No matter what balance of sleep I get, I'm still failing to stay awake during normal activities.
-General disarray and confusion and inability to concentrate. It's getting to the point of where I have to stop in the middle of a sentence because I've confused myself.
-Urinary issues. I thought I had a UTI, so I took a an OTC med to help with the symptoms. Not much pain, but an inability to urinate, and when I could, I was unable to empty my bladder and got no relief.
-My urine has been pale and very cloudy, and has a strange odor... I don;t know how to describe it. It's not sharp.
-I've been urinating much less often (although I drink the same amounts of fluids)
-Loss of appetite. I've been trying to pretend like I was hungry for about 2 weeks now, but it's not working.
-I've been experiencing bouts of extreme nausea in which I dry heave very strongly. To the point in which my muscles tense and spasm so hard that I'm left feeling totally void of energy.
-I have been in a constant state of mild nausea.
-I have general lower abdomen pain, but not trouble with BMs
-I have a general feeling of unhealthiness. I feel weak.

I'm not usually too worried about my health, but I'm scared, you know? I really hurt myself with my attempts, and I want to make up for it by making sure that I seek proper treatment if I'm having issues.

Anyone have any opinions on what could be wrong?
I cannot afford to seek medical treatment if it isn't absolutely necessary, so please consider this.
Should I seek medical treatment/diagnosis?

Any advice is welcome and much appreciated.
