Hi, I'm 17, and these are my symptoms.

I've been vomiting for 2 days, and my stomach hurts. I also have lower abdominal pain, and every time I throw up it goes on and on. I get sicker every time I smoke a cigarette. When I belch I feel like I need to throw up. I don't have a fever and I'm not eating anything new. I've been stressed out lately, I started a new job that I've worried about, and I've been having troubles with my girlfriend to the point where I can't sleep at night. We're good now, but it can get bad.

It's 3:20 Am right now, I'm just wondering if I should drive myself to the Emergency room or not, I have work tomorrow, and the girlfriend is coming over, so if I have a peptic ulcer it can only get worse.

The car has 250k kilometers on it, and the CV joint needs replacing.

The girl said she could replace the joint, get it safetied and then sell it to me.

What should I inspect to ensure that it'll last me 2 years?

It would probably cost 1100$ after repairs.

A dog owner wants to buy their dog 5 things at a specialty pet shop. The shop has 8 different types of dog treats, 6 different types of toys and 5 different pieces of clothing. What is the probability that the purchase will consist of at least one of each item?

In 2011, the estimated population of Canada was 34 699 000. If the government wants to use an alphabetic string using letters of the alphabet for every person in Canada. How long should the string of letters (repetition allowed) be so that every person in Canada can have a unique code?

The population of a small mining town is given in the table below:

Year = 1990-1993-1996-2000-2004-2008-2012

Population = 4000-3010-2400-1950-1625-1400-1220

The decline in population is said to follow a logarithmic model where x = 1 represents the year 1990, x = 2 represents 1991, and so on.

1. Using a regression equation, estimate the population in 1995.

2. An ore deposit is found near the town and experts forecast the population will increase exponentially and reach 4000 again in 10 years.

a) Find an exponential equation that models this growth.

b) By what percent must the population increase each year for the population to reach 4000 by 2022?

Two small towns are adjacent to one another. Town A has a population of 500 people, while Town B has a population of 1200.

Town A has a population growth rate of 4% per year. Town B’s annual growth rate is 1.75%.

When will the populations be the same? What will their populations be when they are the same?

Hello, I've been smoking for a couple of months and now whenever I smoke cigarettes I think about how gross it is, or about the smoke entering my lungs and I begin to gag. Just typing this makes me gag, but I'm already addicted and it pisses me off that I can't smoke.

I know it's all in my head, but I don't know how to take it out.

I have the same issue when smoking marijuana, except I worry that I'll get paranoid so I get paranoid when stoned.

My head is jerking me around, and I don't know what to do. Quitting smoking is not an option I wish to take.

I've been thinking about cutting off my hand, shaving my head, and dressing like a hick.

I've also been trying to change my feelings of different races towards more of a racist approach.

It's really starting to bother me, I'm not racist, and close minded or a tough 'bad ***', and I don't know what to do. I've looked into joining the military, maybe that would toughen me up?

I'm legitimately considering cutting my hand off to be like Merle, should I get mental help?
