Hi and welcome to Beyond Blue.
You asked, Does this empty feeling pass? Someone else might be able to answer this question better than me. In recent years feeling of anxiety and depression became stronger and could not avoid them. And after we (or I) am diagnosed with something we can look back over our/my life and see instances where it was present but did not necessarily notice it for what I was at the time.
I read a book called The Road Less Travelled by M. Scott Peck, a psychiatrist, who had patients whose sessions spanned multiple years. I am seeing a psychologist and have been for a period of 7 months only, but do not see that ending yet. I believe that the process of getting better is a more akin to a marathon than a sprint, and then I will never truly be better except that I have the coping tools when things turn sour. Don't get me wrong, there are moment of some/most days when there is something I can be happy about, but once that moment passes...
You also said... "I often feel pathetic and ungrateful because I am well aware that there are wonderful people out there who are living a life a lot more difficult then mine. What is wrong with me?". From my limited experience, this sounds like cognitive distortions, and this is something that I am working through with my psych. There is nothing wrong with you per se, except that our minds are playing tricks on us, telling us what to think. And the trick then is to be able to recognize this for what it is, and that it is nothing more than a thought. I am still working on that part.
Can you explain more about "the complex mind" part? Do you mean there are lots of different thoughts running around your brain at any moment in time? When I started a BTh recently, and it was in the very first subject I had, when the lecturer said to me "just be careful. I can tell you have lots of ideas in your head". This could have been cause I would play devils advocate to some of the question posed, and would not conform to typical student but I digress.
All these ideas/thoughts were both positive and negative. And if you have negative thoughts, do they come out of the blue or was there some sort of trigger?
How long have you been seeing a psychologist? Does he/she give you homework to do? I am always getting homework to do. But the one thing that works for me are deep breath exercises. Sad but true. But one comment my psych made was that all these things take time, and practice.
