Another example is of a girl I met that I really like. 

She said she will be away for a week and although she said she’ll be back to see me next week. 

I’m getting severe anxiety from thinking of negative illogical thoughts like what if she’s lying and doesn’t like me or doesn’t actually come back next week? 

It’s gotten to an obsessive point where all I think about is her and this situation all day until I can hopefully get reassurance everything is fine next week. 

It’s like severe anxiety until I can see her again, no motivation to do anything until I can get reassurance everything will be just fine. Anyone else?
