@solosunflower I am not you so I don't know, I cannot make assumptions.
I would just ask you to try to hold the faith.
These 'totally trapped', 'lost everything', desperate feelings come to all of us as new, (and older, further along the way mums.)
Your very tiny baby's total dependence on you for his/her very survival gradually eases, so so gradually. All your feelings of despair will be very much exacerbated now by tiredness, weeks of interrupted sleep, many, many times a night, inadequate nutrition through no fault of your own.
Set up quick online deliveries if you live somewhere where that's feasible.
Might be worth temporarily signing up to Amazon Prime for quick, fresh, nutritious food deliveries. You deserve some treats, after all.
Have a look at an online food retailer called Bother too, some very good deals. I discovered these sorts of useful companies during the various lockdowns we've had.
Taking practical steps to help you get through this time can really empower you to think: I can do this, I will do this..
Simple question: has your baby responded to anything like rattling a tiny baby toy near her/him, or has s/he turned her/his head to follow a musical mobile placed safely next her/him during a nappy change, a quick, non-smelly wee nappy change... or... those other ones?
By the stength you have shown throughout this incredible journey of yours, I believe you truly can do this
