I've got social anxiety disorder (SAnD) so I know how you feel. Tasks that other people would find easy or nothing were the end of the world to me.
Don't listen to the people who say "first world problem", they're not worth a minute of your time. Ignore the people who don't believe you when you talk about anxiety disorders, they're not worth your time either. Ignore all ignorance about anxiety.
Work on your anxiety when YOU want at YOUR own pace, don't let anybody push or force you.
It's taken me years to the point I'm at now, but just know that you can do it. I don't feel comfortable talking about the majority of my anxiety-related experiences and fears, but I used to be terrified of going into a fast-food restaurant and ordering food, almost to the point of tears.. now I'm able to do that AND eat in the restaurant which is a massive step for me.
I did this by going at my own pace and ignoring the negative people in my life like my dad, who are in the old-fashioned mindset of "if you can't see it, it doesn't exist" when it comes to mental disabilities.
