what do anxiety meds feel like?

hi everyone! i’m 15 and i’m going to start anxiety meds soon. i’ve had awful existential anxiety since i was ten, but started therapy a few months ago and i’m being referred to a psychiatrist to help me out. i’m not exactly sure what kind of meds i’ll be on, but i was wondering what it generally feels like. how does it help you? does it change your thoughts? do you not care about the things you’re anxious about because of them? i’d love to know! tysm!
