Anxiety

My anxiety is so terrible. I am so worried about every symptom I have,Christmas eve I had awful awful gas pains that had me in years . And for the last few days I've been kind of crampy which I just assume is growing pains since I'm almost 18 weeks . I google everything even though I know not to, then I freak the fuck out. I have only felt a flutter once at around 16 weeks and nothing since ,I think when I feel consistent movement and after my 20 week scan I I'll prob feel much better. The anxiety is killing me though , it's my first baby and I never know what's normal or not. Anyone else feel this way ?
