Why didn't I do this sooner?

Many times over the last few months I wonder why I didn't do something sooner. Often thinking if I had done this at X point in the recent past I could have avoided Y situation that caused me stress. The mantra I have to then tell myself is that I am doing it now and I better stick to it. Don't half ass and don't back down because I am depressed. Push through to the accomplishment of getting it done. Things often take longer than we imagine. Especially if we are overcoming illness and pain(emotional or physical).  Despite frequent detrimental events I am still breathing. I may be broken and alone and hurting but I am alive and I will survive.
