Sleep help!!!

Ladies I know we talk about this but I need help!!! Little girl just turned 5 months we are on over a month of horrible sleep I don’t know what else to do! She wakes up multiple times - I already suffer from severe insomnia and have been struggling to get back to sleep once she sleeps. So my problem is - letting her cry it out / fuss until she soothes isn’t working for me because then I’m wide awake and can’t fall back to sleep what so ever. So as soon as I hear her awake I go patt her butt put pacifier back and she’s usually right back to sleep.

Is this not the way to go about things so she sleeps thru the night? I dunno what else to do! I just need sleep it’s taking a toll on me at work I can’t function properly I swear I’m gonna break
