An interesting site, https://www.patientslikeme.com/, if you suffer from any number of conditions, ranging from Autism, Bipolar Depression to Migraines, Thyroid issues, and over 2,800 medical conditions. A partial list can be found at: https://www.patientslikeme.com/conditions. If you don’t see a condition, you can search for it.
The site is free to use and I use it to track some of my medical conditions. I receive a daily e-mail that allows me to enter information on how I am doing every day. I can also do monthly updates and make other notations on a regular basis as appropriate.
