i've tried zoloft, cipralex and welbutrin; all useless for anxiety, in fact they worsened it and gave me side effects. Antidepressants are hardly effective compared to placebo for depression, let alone for anxiety. I think it is a big sham that doctors push SSRIs for anxiety at all as they cause anxiety for many people even after they start working. But if it works for someone then that's fine with me.
You really should only use benzos if you are having a panic attack, try everything else first, like exercise, eating better, proper sleep, environmental changes, therapy and laying off caffeine. If you feel like you are going to end up in a psych ward then consider going on benzos. Once you go down that route it is extremely difficult to go back.
^xanax is for panic attacks, not great for general anxiety. I highly doubt you need xanax and it's not something to take lightly. It can either be a valuable tool or it can ruin your life and your mental health for a very long time.
