Maybe your husband's word choice was poor, but I too can appreciate the message he was hopefully trying to convey...
No we can't pull ourselves out, but we can try to fight tooth and nail from every angle, as mentioned above.
I was struggling with a depressive episode for about 3 months and I really believe that the only reason it didn't get as bad as it threatened to is because I kept fighting it.
I socialized on days I wanted nothing more than to watch the world burn, it was god-awful but it helped keep me out of my own head for a few hours at a time.
I had an appointed "General" who I'd report to, she'd "make me" bath, wash my hair, clean my room, walk to the park or sit in the sun for a set amount of time and I had to send pics as proof.
It helped having someone to answer to, and she knows this about me and that's why she spent time ordering me around...
Wasn't easy, especially since she's my baby sister, but once I make a commitment I stick to it, so our little agreement helped me immensely...
Upping my session time in therapy also benefited me.
So while I didn't pull myself out of it, nor could I, knowing that I was actively fighting it helped in its own way. And because I was fighting it, I didn't give it enough time to fester like it would've, had I not practiced so many opposite actions and just did what I felt like doing.
Which would have been rotting away in my dark bedroom.
Even my T and closest loved ones commented on how differently I was handling it, and how much better I was coping this time around...
That validation was also some much welcomed positive reinforcement..
So it definitely did make a noticeable difference to actively decide to not just take it lying down... Literally.
I'm sorry you've been hurting so much, I really hope that the sun shines on you soon.
