I am so sorry things have been hard for you. I overdosed four or five months ago due to health scares and anxiety, and it's horrid.

Health wise, is there a clinic you can get to? It's good to have blood work done (though I know you're sick of it, trust me, I know). If you don't want to explain to a stranger that it was an OD, simply say it was an accidental medication overdose and you're just concerned with the side effects. If you had bloods done and it wasn't specifically for the OD, they wont be looking for certain things that could happen after an OD. My blood work was drastically different after my OD, looking for certain enzymes, etc.

Definitely reach out to your doctor and explain what happened. A physical will be good too. After my OD I had blood work, a physical, and a referral to my therapist to increase therapy time to twice a week.

Take care.
