Long-term Mental Health Concerns.

I've been experiencing the following symptoms : - Constant fatigue and tiredness - Difficulty concentrating, easily distracted - Overwhelmed by racing thoughts - Unable to get out of bed due to feeling of heaviness. - Significantly reduced reading speed due to attention issues - Recurring thoughts of self-harm - Sleep problems: unable to get more than 4 hours. Last year, I made lifestyle changes to address these: - Quit smoking - Deleted social media, reducing screen time significantly Despite maintaining these changes for months, symptoms persist. I'm now considering professional help. Questions: 1. Should I schedule a visit with a mental health specialist? 2. Do these symptoms suggest a mental health condition requiring professional attention? 3. Is this normal stress/lethargy or something more serious? I'm seeking advice on whether I need professional evaluation and potential next steps. Thank you for your guidance.
