How can I increase my chances of getting a date? And maybe, are my assumptions valid?

To increase your chances of getting an appointment, you may want to consider reaching out to a different clinic or using online services that offer appointments without the need for a referral. It's important to communicate your symptoms in detail and seek professional help for a proper diagnosis and guidance on how to address your concerns. It's also advisable to educate yourself on mental health conditions but always consult a healthcare professional for an accurate assessment and treatment plan. Good luck with your journey towards seeking help and finding answers.
