You know, I was thinking, and there is really nothing terrible about surrendering to situations and external circumstances sometimes. By surrender I do not mean "These things make me feel like shit, and I surrender to the fact that I will always feel like shit" - Creating your own self-fulfilling prophecy. But keep in mind you have NOT always felt like shit. When we're in a twisted, negative mindset, everything looks worse. Even the past looks worse. Our moments of happiness seem cheap, phony and unfulfilling - But at the time, they were no such thing. Depression puts a hefty, gray and cloudy filter over everything. It's a lot like an alternative to that little message on the sideview mirror: "Objects in mirror are closer than they appear". When you're looking at these mirrors, your skewed perceptions make them appear far more detrimental than than they really are. The days, hours and minutes that you felt good, you were reflecting in another mirror. Whenever I feel down, after I've wallowed a good enough time(for me, anyway), I ask myself "Well...What are you going to do about it? Are you going to sit here and give into this old, miserable and painful way of thinking, or are you going to try something new and see what happens?"
Remember this, dear - You ARE laid up in the house right now. This is such a huge, huge part of the hopelessness you feel right now. What is that saying..."Idle hands are the devil's workshop" ? Something like that, I never get those things right. Time can be our enemy or our friend, your choice. So, you can't work or exercise - What can you do to fill your time? Do you enjoy painting, writing? Any types of crafts? What else does Snowshine find pleasure in? I would think about making a list of new self-soothing(and old) activities that you could try.
If you can't get the body moving, you must get the mind moving. Sitting stale for too long is dangerous, and is a breeding ground for negative thoughts and reinforcement.
Someone posted this link, and I have become partial to the BPD tool section(links on the right) -
http://www.dbtselfhelp.com/html/the_bpd_tool.html Have a look, it's incredibly useful.
