I've had that psychiatrist too. Eat better, exercise, take your meds earlier, blah blah blah. He also told me I can seek another opinion, so I did. So far so good. Therapists are tricky too. My last one was good, but I don't think we were getting anywhere. So I'm still on the hunt for a new one. Between med adjustments and trying to find a therapist, I just take it one day at a time. It's all I can do for now. I hope you're able to find better doctors.
Your ex sounds like an *** and should go kick rocks. Block him however you can on social media, the phone number...whatever. That negativity does not help (I'm sure you already knew that). I'm exhausted too, pretty much gave up on trying to find a therapist, but we'll see. Good luck and please take care. We can get through this.
