i’m trying to help myself

my anxiety spiked when i was on nexplanon and i got it removed. i’m 18, haven’t had anxiety since i was 9. it’s been out of control. i feel like i’m afraid to drive (that’s where my attacks happen) i always feel like i’m dying and imagining the world without me. no one at my work takes me seriously ( i’m trying to become a lead) and now my mom said “get over yourself” when she suggested this in july ?! i feel like it’s only getting worse.
