Your symptoms of persistent overthinking, difficulty sleeping and repeatedly elevated BP around 150/110 should be assessed together. Stress and poor sleep can contribute to difficulty controlling BP, but BP at this level should not be attributed to stress alone. A reading of 140/90 or higher falls into stage 2 hypertension.
Homoeopathic treatment can be considered for the individual pattern of insomnia, continuous thoughts, anxiety/restlessness and associated symptoms. A detailed case assessment is important rather than simply prescribing a sleeping medicine.
Next Steps
Please share your recent BP readings, current BP medicines (if any), how long you have had insomnia, your sleep pattern, the nature of the continuous thoughts and any associated anxiety/palpitations.
I would also recommend continuing appropriate medical treatment and monitoring for your BP. If you are not currently taking treatment for persistent BP around 150/110, please consult a physician for proper evaluation and management.
Health Tips
Do not stop or replace prescribed BP medication with any alternative treatment without discussing it with your doctor.
If your BP reaches 180/120 or higher, repeat the measurement after a minute. If it remains that high, seek immediate medical advice; if it is accompanied by chest pain, breathlessness, weakness/numbness, vision changes or difficulty speaking, seek emergency care.
Your insomnia and continuous thoughts can be addressed systematically once the complete pattern is understood. A detailed consultation would help determine the appropriate individualized approach.
