Understanding Change

I am led to a belief that everything is in a state of flux, and to a certain extent I certainly agree with this fact. In contemplating my mental state, I'm worried that I am stuck in an unshifting state - so I am relying on this fact about the impermanence of our mental states to deliver me from my suffering. Afterall, I have know memory of what it felt like when I was 5 years old... and perhaps one day I will no longer be able to recall the pain I am feeling today. I remember when I was 22 I had a very intense relationship that completely fell apart on me. At the time it felt like I would never be able to get over. I couldn't fathom things getting better after that sort of trauma. Nevertheless, after a few months of severe depression the veil started lifting. Now, I do think that depression is a more temporary type of state than the one that I currently reside in, however, in a year or so this may also be a vague memory. I have done reading about what is called state specific memory. Namely, that when you are in a specific mental state you are unable to access a certain experience. Once this state shifts you can re-access feelings and emotions that you thought were long dead. This may be the case! However, one cannot grasp or cling to the past. Unfortunately, that time is now history.
