PTSD & Anxiety

After going through a traumatic incident 2 months ago, I was diagnosed with Generalized Anxiety and PTSD. My doctor advised me to follow up with a therapist but my parents refuse to take me when our appointments are scheduled. I'm 14 years old so I cant take myself & my parents are very closed off frok other family members. I cannot speak to a school councilor because my school handles these issues in a very unorganized way. (basically just letting my parents know what they already know). I dont want to continue on with these high levels of anxiety & I want to be a normal kid again. I know thats what my parents want too, but instead of getting me help they'd rather pretend that everything is okay with me so they dont have to deal with my burden. Any advice on how to cope with the PTSD & Anxiety without going to a proffessional or taking medication? (medicstion I was presecribed makes me hallucinate). I'm really starting to lose hope.
