Pregnancy has been so much harder than I thought it would be!!!

Is anyone else having a really difficult time??  I never thought pregnancy would be this difficult!  I'm really struggling!!  I'm 7 1/2 weeks pregnant and for the last 10 days, I have thrown up every single day.  Some days, all day.  I have no appetite and it's a lot of work to get anything down.  The cramps are uncomfortable but not too bad.  I had the worst headache for about 4 days straight, but it finally went away!  And now I am so constipated it hurts!!  Never had constipation before like this!!!  I'm seriously ready to lose my mind!!!  I didn't think it would be really easy but I didn't think it would be this horrible!!!  Am I alone???  ?
