Thank you for writing. You don’t need me to tell you that your symptoms are very serious. You could have caused an accident with disasterous results.
By all means, go to the Emergency Department of your local hospital. Take your letter and this response with you. It will help the staff understand you. Do make sure that that a thyroid screening and a check for vitamin deficiency are included in the assessment. Sometimes symptoms like yours are related to one or both problems. Do tell them if you are taking medications for bipolar.
If all is physically okay, then you absolutely do need to see a mental health professional. I did an internet search for low income mental health services in your area and found several agencies that offer low cost help. The ED may also be able to provide you with a referral.
Please follow up. You deserve to feel better. You don’t want to live with the guilt that comes with accidentally hurting someone.
I wish you well.
