We all arrive here with differing experience and views, along our own personal journey of pain; it is understandable that at times we feel less hopeful about the future or how much impact our condition will have.
These are a natural thought process as we adapt to this new life and deal with the daily issues of not being able to do what we once did. Looking longingly into the past for us may bring back how much we miss, rather than what we have achieved. The achievements of the past are not a mirror into the future and do not reflect what we are now able to do with restrictive function and limitations.
Dwelling on the past too much is using energy that could be used in a more productive aspect, it takes equal measure to look at things negatively as positively.
I too had moments of depression where I looked too far into the future and designed an unrealistic notion of what might happen, in allowing the what if fairy to cloud my judgement. It was a self perpetuating outlook, the more negatively I approached aspects the more frustrated and disjointed I became. My opinion is that this is just a phase that we all go through, the danger is in becoming a person who is more negative than they need be, in action and words. In reality as my well-being improved, so did my assessment of my own future, although my limitations are still with me I view them differently than I did, I have moved on.
We all have pride and emotional attachment to what we used to be, and letting go and living with what is left never easy, our survival is in the future ahead of us, not in the past or marking time while reminiscing.
We are all holding hands together marching to new opportunities.
Take care John.
