User Testimonials for Lower energy levels
Female, 10s
Ubie helped me obtain the right care I needed by its very detailed description of my symptoms and the possible conditions I could have. I was able to understand my symptoms before seeing a professional. The doctor is going to ask you for your symptoms, and I would've had a hard time describing them without Ubie. I had various symptoms such as forgetfulness, suicidal ideation, mania preceding a depressive episode, no motivation, feelings of grief, low self esteem, decreased energy levels, history of self harm, among others. I originally went to my doctor and she referred me to the psychiatrist. Ultimately, Ubie helped me find out what I don't know about myself, and that way I could get the help that I needed.
