I agree with others that we really shouldn't be focusing on goals with meditation. The goal itself is an attachment, and can interfere with the zazen itself. I also agree that having a good teacher or friends in a sangha can be very helpful...the Buddha himself placed great emphasis on sangha as being integral to the practice. Going it alone can be like flying at night without a compass. Yes, you're meditating, but you may be spinning your wheels without the help of a good teacher and/or sangha to support you.
One other thought that I had in response to your postings is to be aware that zazaen, and the energy of zazen manifests not just on the cushion, but also in daily life. Since starting to meditate, are you maybe a little more patient with people? Are you just a bit kinder to yourself and those around you? You mentioned some changes you have made in your life: these are a big deal; even the change in your diet is a big improvement, and may be part of the path toward lessening anxiety.
Finally, take a look at some of the Mindfulness Based Stress Reduction articles and youtubes out there (Jon Kabat-Zinn especially). MBSR is a meditation based program to help people with anxiety, dep, and PTSD, as well as to help nearly everyone navigate the stressors in life. JKZ does not call it meditation or Buddhism or Zen, he teaches in a secular fashion, but the teaching is at the heart of zazen and vipassana. It's a style of meditation and thought designed especially for cognitive issues like anxiety.
From your posts, it seems to me you have made changes, and reached goals, and yet you're just not seeing these positive changes. Zazen is not like weightlifting; doing it every day will not give you a bigger bicep in two weeks. Sticking with it though, with a good guide and faith in it, will yield huge results. Just don't focus on these goals...


Oh my! Meditation will not make you feel better. Buddhist calming meditation will enable you over time, and this varies very greatly for different people, to
