Dear CourageofSnow, I'm sorry to hear you've been going through a hard time. It's wonderful that so many people here have offered you advice and caring words. I'm glad that you have been feeling a bit better since sharing with us and since talking to people in your life about what you're going through. That's a big step, and it's a very positive step. Acknowledging that you need help and that you need support is a very difficult step to take, especially when you're already feeling, as you said, like a burden, selfish, lazy. I know exactly how you feel, too - I've been where you are many, MANY times (and probably many more times to come).
You're not selfish, lazy or a burden, though - like others have pointed out, you're unwell. You're dealing with an awful lot. Just because what you're going through may not be visible, doesn't mean it's not important or doesn't exist. Taking care of yourself is in no way selfish or lazy or burdening! It's vital for your health! It's impossible to keep giving to others when you don't give to yourself.
Something I sometimes do when feeling suicidal or feeling like I'm dissociating or need grounding: I put a rubber band around one of my wrists and I snap it just hard enough to cause a sting. It actually helps immensely for me with suicidal ideation or self-harming thoughts; and the surprise of the little sting is enough to pull me back to the present and focus on what's going on around me. This of course may not work for you at all, but I suggest it just in case it might. :) *offers gentle hugs* :hug:
