Hi, I'd like to help you with your question.
Being that you are feeling so anxious about possibly getting Schizophrenia, then it is highly unlikely you have it. Most people who develop schizophrenia are not highly anxious before hand, nor do they display the depth and insight that you have. They also do not write their thoughts out clearly like you did, because their thoughts are disorganized and they are not able to communicate their needs with any level of insight or depth. I have treated many people with Schizophrenia and you are not exhibiting any symptoms that I can tell, just from your question.
Adderall cannot induce schizophrenia. It is a medication that helps reduce symptoms of ADHD but it has never been known to induce schizophrenia. It can cause anxiety if you have a reaction to it, so you may want to check with your doctor about possible side effects you may be having. But any research I am aware of regarding the origins of Schizophrenia do not include medication as a cause.
If it makes you feel any better, consider getting an evaluation by a qualified therapist. Anyone experienced with schizophrenia will be able to reassure you that you are fine. If anything, you may have mild anxiety just from the stress you are experiencing, but that will go away when you feel better about not having schizophrenia.
I hope this has helped you,
It is always better to face your fear. That does not mean you need to do it alone, though. Talking to others about your fear and getting assistance always helps. Reassurance is always good as well. But facing your fear will help you learn that you are ok. Facing your fear takes the power of your fear away and helps you gain confidence.
The internet is ok, but take it with a grain of salt. It is always better to check with a professional who can talk with you about your personal situation.
You may want to check out the book The Anxiety and Phobia Workbook by Edmund Bourne. It is excellent and helps you work on facing your fears.
I am very glad to help! Anytime you need to talk, I'm here.
