Here is an article that you may find interesting about using writing to honour our struggles as a form of healing. While I do not abide to any sort of organized religion, I do see the significance of recognizing a higher power during recovery (and life after/between illness).
I use to see myself as a Christian but my illness really quelled that idea. The Christian outlook on God (or at least how I always understood it) was that He only gives to us what we can handle and that He has a higher purpose for His actions. While this is all very well in theory, in the midst of my depression I started to think, what kind of asshole would put this upon those he supposedly loves? (Not to mention that it drives many to suicide for which He then punishes them for)
I still consider myself a spiritual person but believe in a more abstract form of higher power; more like there exists a power or powers that can guide and comfort, but has little power over peoples actions or their fate. I also believe my ancestors are with me and I pray to them when I need comfort or guidance. I cannot blame my life's problems on a higher power such as these but can find strength in them being there for me.
How does religion tie into your healing?
