Hello Truetomyself, one way to overcome agoraphobia is by trying a technique called desensitization which you can do by yourself or with a specialised counsellor, but it's not up to your parents to decide whether or not you should be taking any medication, that's a decision between you and your doctor and they don't need to know if you are taking it, if you are able to get the help of someone who can purchase it for you.
If your father is causing you to feel like this, then are you able to move somewhere else.
Geoff.
