I have these anxiety attacks because I worry about the littelest thing. I have a mole and I am scared its cancer. I also worry about many other things. I didn't sleep at all last night because I was thinking of this. I tried calming down and slowing my heart rate but it didnt do anything . I always feel scared and overthinking things and it freaks me out. Any advice please?I havent been able to sleep in the past 2 days. I only got like 2 hours.
