How do i get my lashes to stop falling out?!

So i have a bit of an issue with plucking hairs, i think theres a name for that but a while ago i plucked a ton of my eyelashes (the ones that were bothering me) and now theyre extremely thin and fall out super easily. Im worried my eyes will literally be bare in these next couple months. Ive tried look for eyelash serums but theyre all SO expensive. Is there a recipe i could make my own??
