If you've been experiencing difficulties with completing assignments you know you can do and struggling with studying and organization, it could be worth considering getting tested for ADHD. The symptoms you described, such as giving up on tasks and needing support with studying and staying organized, can be consistent with ADHD.
However, it's important to remember that only a qualified healthcare professional, such as a psychiatrist or psychologist, can provide a definitive diagnosis. If you suspect you have ADHD or any other medical condition, it's best to seek professional evaluation. They will be able to assess your symptoms, consider your medical history, and conduct appropriate tests to determine if you have ADHD or any other underlying issues.
Getting a proper diagnosis can be beneficial as it can lead to a better understanding of your challenges and open up opportunities for tailored support and treatment, which may include behavioral interventions, counseling, and, if necessary, medication.
If you're a student, you may also consider talking to your parents or guardians about your concerns, so they can assist you in seeking professional help.
Remember, seeking help is a positive step towards understanding yourself better and finding ways to overcome any challenges you may be facing. It's essential to address these issues so that you can reach your full potential academically and in other areas of life.
