Im not asking for a diagnosis, I know I need to go to a professional about that I just need to talk to someone about this even if that person may be a stranger on the internet

As a little kid like ten years old before I knew what anxiety was I used to wake up in the middle of the night feeling like my heart was gonna explode and that the world was crushing in on me and distracting headaches, I stopped telling my parents about it and started hiding it after my parents told me I was a hypochondriac and that I was making it all up, this actually gave me a lot of struggle with opening joy to people in the future because of this incident,  the feelings eased up a bit during my first few years of high school but then came back just as bad when it got to year 9/ 9th grade  and expecially with lockdown, I don’t want to tell my parents because they will just tell me I’m making it up again and I can’t tell my friends because I don’t wanna be that person that makes up mental illnesses without getting assessed, or to make them uncomfortable or annoyed at me for talking about it I just feel like I’m stuck in this loop with no way to get out except wait a 3 years till I can finally book a therapist, because I honest to god don’t see any other way of dealing with this
