help me please

i have sever anxiety. and it shows in many forms.

hands shaking terribly,
voice tremble,
stomach bubbling/ knots,
chest pain,
sometimes blushing of cheeks
&
can’t sleep

i have had it for years and i am so sick of it. i feel like a slave of my own mind. it’s very annoying bc i want it gone forever but my brain won’t let me. someone please help me get over it.
if you’ve had anxiety before and you’ve gotten over it please help me and tell me your remedies.
i’ve tried meditation it helps in the moment but i don’t have time to be doing that everyday and it’s not realistic. if i’m in public and can feel my anxiety starting i can’t just sit down at work or in the middle of the store and meditate.
if there’s any supplements that i can take that isn’t prescriptions from a doctor or anything i just need help.
i recently got a new job and i am excited to start but my anxiety is making me so stressed and nervous. last night i couldn’t sleep bc today was my interview and i was nervous about it.
i got the news today that i was hired and ever since last night my stomach has been bubbly and i can’t help but think about when my first day will be how it will go etc. i know thats partially normal for most people but i know mine is my anxiety. bc it happens to me in any situation.
i know a lot of people will tell me to try to control my mind but i don’t understand how to do that. i really can’t get over it. i just want to enjoy life i want to be social with people without being so scared.
i cry about it a lot and i’m embarrassed. i really hope people can’t notice i have anxiety. i have depression, anxiety and adhd. it’s so hard and i’m only 20 years old, female. i have my whole life ahead of me and i can’t deal with this feeling forever. i even get anxiety when i go on social media too, when i make a comment under a post i will eventually delete it bc i will start thinking “people can see your comment they will know who you are” and then i think “if they don’t agree with you they’re gonna leave hate comments” and my anxiety eventually shows up and wins and i will delete the post or comment. i worry what people think about me a lot. i deleted instagram like two weeks ago to try to help my anxiety since it can give me anxiety alot. this is the only form of social media i have besides youtube. i don’t even have pictures of myself on instagram except for my photos in my “highlights” tab. i do that so people can’t see me at first they have to look. i can look back at my childhood and point out alot of things that would’ve caused me to be this way but i don’t care about those incidents anymore bc that was so long ago. i feel those feelings should’ve passed. how am i still dealing with that all these years later and it turns into long lasting draining anxiety? i don’t understand. it’s not fair. i literally have it right now typing this i’m scared what people are gonna say. i see other people my age just living life doing things and having fun. i want that but i am so nervous. i’ve tried praying to God about it, i’ve tried crystals (ik that’s against God but i’m trying all i can) and ofc meditation like i mentioned before ^ nothing helps me. i haven’t had friends since i was in 8th grade. i’ve made school friends since i’ve moved out of my old town but my anxiety stopped my from hanging out with them outside of school. i want to live.

please someone help me.
