I have been exposed to manganese toxicity

I'm 17 years old and live in Ukraine. I am seeking medical advice regarding neurological and mental health symptoms that I have been experiencing for a long time. I have chronic anxiety, panic attacks, depressive symptoms, cognitive impairment (difficulty thinking clearly and focusing), problems with coordination (especially while driving), and occasional hallucinations. These symptoms significantly affect my daily functioning and ability to study, work, and live independently. I suspect that long-term consumption of well water may have contributed to my condition, as the water quality in my area is poor, and there may have been contamination. I am concerned about possible exposure to toxins or heavy metals and their effects on the nervous system. I do not currently have access to paid medical care and would like to know what possible causes could explain these symptoms, what conditions should be ruled out, and what basic steps or tests I should try to get first if I can only access limited or low-cost healthcare. what should I do? It affect my daily life. It's freaking exhausting
