10 weeks pregnant

I guess I just need some advice. I have been so sick since week 4, throwing up 4 times a day sometimes even more, not eating or sleeping and just being miserable and in pain. Feeling so sad and hopeless. When will this end? This pain is making me someone I’m not. I wish I could be excited but I can’t help but be scared for my next appt that something is wrong. Is this normal??? Ugh!
