i want to work so bad but how do i tell them im agoraphobic

Hi I’m currently undiagnosed but am so sick of the way I’m living that I’ve decided I seriously need to get help. I need advice on 1. How to tell my parents that I need help and 2. The process. The first part is hard because a couple years ago I talked to my mom about having OCD but she brushed it off and said “everyone has anxiety” so I just never brought it up again. I’m also a bit ashamed for some reason, I don’t know why, to bring it up to them and I feel scared. For the second part what’s the process of getting diagnosed and getting medication and therapy. Where do I get diagnosed and do I have to start therapy before getting medicated? Thanks so much for the help.

okay so I’m 18, I’ve always been kinda a homebody , especially recently starting lexapro made my anxiety worse at first ect. I feel so scared to be in the “ real world” because I feel like I’m not independent at all:/ I’ve never had a job I had 1 at 16 for 2 weeks and it wasn’t to bad. I can drive , but it’s kinda hard for me , I get scared of thinking of the future and independence “what if I’m not capable” “What if my mental health doesn’t allow me too” ect ..:/

17f I work at the restaurant as a cleaner, pot washer and a kitchen assistant. My job already made me freak out a bunch of times because couple times while cleaning I was kinda near children and my POCD is very severe just being around children makes me anxious and later I sometimes have false memory ocd that I touched the children even though I didn't And my boss said that in July I will probably be promoted to a waitress. And I'm terrified. It's a busy family restaurant in a city center and people constantly come here with little children. It's one thing to work in the kitchen and cleaning during closing shift, I still see children sometimes but I can avoid accidental physical contact for example. But as a waitress it will be hell on earth. I will need to walk between tables outside where children are constantly running around and if I have stuff in my hands I won't be able to move so fast to avoid touching them I need this job so much and its hard to get a job as a minor here but this will fucking ruin me. I can already see how I will have a mental breakdown because I accidentally touched the child while working and convinced myself I did it on purpose.
