What should I do?

I been having bad anxiety over random stuff, driving, traveling far, being alone, sometimes even just sitting at home doing nothing. I been diagnosed with hashimotos but I’m confused on which symptoms correlate to my diagnosis. I lost 30 pounds since July. I have a goiter in my throat, I have mild anxiety, I have super bad hormonal imbalance when my period is coming my anxiety gets so bad and I have headaches a lot. Always hot and body aches. What should i do?
