Help please!! Strange behavior from my seabright..

Well its really the only thing that makes sence. We've been feeding her baby formula and vitamins and its not helping. it gave her a little strength at first but in the last 2 hours she's taken a bad turn for the worse

Beeper is getting worse and I can tell she is miserable. I've been feeding her by hand all this time and now when I put the food in her mouth she doesnt even try to swallow. I think she has given up.. :'( If she survives the night and she is still worse I feel like I have to put her down for her own sake. What are my options? I don't deal well with death and I have no idea how to put her down in a way that is painless for us both. I'm not sure I have the strength to do it :'(
