In many ways I feel afraid to admit an element of recognition. However, I'm not entirely sure if it's a very helpful or potentially destructive perception. Perhaps an equal balance off the two very valid points would make me more comfortable
Depression may well have become a part of who you are today, I think that could be the case for many of us. However, equally valid is the fact that depression is still as much an illness as say something like diabetes. With respect, I think it is the illness that is encouraging you to think in this unbalanced way.
Of course, there are many who decide, successfully, not to treat their depression with medication, but, if you're seriously considering suicide as a very realistic possibility, then, in my humble opinion, you need your medication more than ever right now. We all make the mistake of thinking the meds are doing nothing to help, but perhaps it is that medication which keeps you from carrying out your thoughts.
Hope you're doing ok
