If mental health matters, then the mental healthcare system needs to practice what they preach instead of just say things to look good for their psas. There’s so many homeless people in my town and I easily see myself becoming one at this rate. Do what you can to take care of yourself. Try to avoid shitty drs and therapists. It’s not always easy.
For extra peace of mind, OP can consider getting a TDS (“Total Dissolved Solids”) meter. My boyfriend got one and uses it to figure out when we need to change water filters.
