My approach to treating my own anxiety now, is to apply techniques that calm my nervous system. When our nervous system is overactive, anxiety is the cumulative effect of the cause (not the cause itself like the mental health field has you believe). Think about it. Our nervous system is controlled by our metabolic hormones like insulin, cortisol, leptin, gherlin, progesterone and estrogen. Our nervous and endocrine system gets out of whack and anxiety is the result. Having anxiety for my entire life I tried anti-anxiety medications and even SSRIs (which don't work for anxiety it turns out). So, I did some research and for myself, decided that to calm my anxiety down, I need to calm down my nervous and endocrine systems. That means - for me, anyway - getting enough sleep, writing down my thoughts before I go to bed of what my worries are, not using my cellphone 30 minutes before I go to sleep (that one's hard), not eating a lot of junk food, trying to get exercise (walking), keeping a list of goals I need to get done every day or week, making sure to calm myself with watching or reading something funny and get social time (chat with neighbors or friends). So far when I stick to these routines, I notice a decrease in my anxiety. Does it always work? No, sometimes I'm anxious and I have to use DBT/CBT on myself. I avoid the use of anti-anxiety or SSRI meds b/c those never helped my anxiety. I found that changing my mental and physical routines is what worked for me instead of a pill. I realize that may not be realistic for everyone, but it's what's worked for me.

Also, anxiety can be a side effect of a health condition too. Like with your thyroid, or if you're low on Vit D or low on Iron, etc.
