To answer your question, YES, you are "getting better." I say that fairly confidently with only knowing a few details of your situation.
You are on a very similar course as I am, and we should count ourselves fortunate. You say you had the blood symptom checked out and that it is being taken care of so I am assuming that here. The rest is usually anxiety. I've felt light pain/burning/tingling sensations all over my body. It's odd and not pleasant, and is almost certainly due to high anxiety only. By the way, you should thank your doctor because he is very right. It is best to tough it out if the suffering is not too intense. When you recover without medication through "acceptance," you know the way out. So even if you do stop feeling the symptoms, then they come back, you will know exactly what kind of attitude to have and they will come back less and less frequently. I was so bad last January that I should have probably taken medication, but I toughed it out and now I will never go back there. I still have lingering anxiety but it is so much more tolerable, and I notice it getting better week by week, with a setback here or there.
It does feel like you are going in circles sometimes because you'll have a good day or a good week, and then you might feel like you're back to square one a day later. But you're not, you are recovering the hard way (which is good), so let your body slowly keep healing itself.
Whenever you catch yourself with anxiety (which right now still might be consistent), just think "I can do nothing wrong, everything I think or do is right, I don't have to force myself to think or do certain things to recover." This is a more fool proof way of an acceptance attitude. And it's true, if you are letting time pass and have this attitude, you are taking the absolute shortest path to full recovery. You might have preconceptions about what you need to avoid or pursue to recover (such as a certain diet or medication), but the key is to stop trying to recover and do your best to accept, thinking you can do no wrong since your body will recover on its own without your assistance. When you think you can do no wrong, you start letting go and your body heaves a sigh of relief!
Even with a perfect attitude, you will still have setbacks so try to expect them as a part of full recovery.
