I'm dying....

When I first found out I was pregnant at 5 weeks, my symptoms weren't very strong and over all I felt fine but currently I am 7 weeks and I absolutely feel like I am dying. I can't tell if I'm sick or if it's just the first trimester that everyone always complains about. I'm sneezing and have a runny nose, this morning I woke up with a terrible sinus headache, over the past week I've had a very upset stomach, and today I had my first bought of morning sickness. Did anyone else feel this dreadful at 7 weeks?
