It is the depression talking that is making you feel like you do....from the feeling sad, no joy in anything, everything pointless, same groundhog shit, different day, Christmas/family holiday/anything same old same old, no use, everyone feels down, no one can help. I so identify with all of that. I had that for several years. I would in no way think that there was anything anyone could say or do that would make the slightest difference. I would still be me. Nothing would have changed, so why bother?!
I remember when I finally told the dr and had some counselling during my first session she asked "have you ever felt like life wasn't worth living?" And I sort of chirped up happily "yes!!!" As if she'd been reading my mind and it was more like a "you read the daily mail 20 times a day too?" "Yes, me too!!!" Type conversation. And then she wrote down the number for the Samaritans and I thought Huh.....oops, guess everyone doesn't feel like me! Which is sort of obvious now I'm mostly out of the quagmire and disordered thinking, but seemed perfectly normal to me then. Feeling soooo down, thinking of your exit strategy is NOT what everyone feels. Sometimes people feel down, yes, but it's not their default position.
Even you justifying not going to the dr as it's for sick people....I think it's mostly that you don't feel you deserve to be helped. Infertility is bloody awful - a real downward mindfuck. It messes with your self esteem like nobody's business.
Please think about going to the GP. Counselling was good, but for me actually antidepressants changed my perspective radically, and within a fairly short while. I think that if you've been struggled for a while your happy receptors and ability to make happy chemicals are just so depleted that sometimes you need a bit of a chemical reboot.
