Worried my lo is behind on everything 😭

I feel like she’s behind compared to other kids her age. She doesn’t crawl kinda just pushes off backwards in a push up position. Pushes herself back if she sits up too long (to the point she would def smack her head if I let her fall). She can stand for a few seconds unassisted if I stand her up myself. I feel like I created this problem cause I take her to work and she’s been in a routine since a few months old so I def made her lazy 😔 literally the only thing she does herself is roll around from back to belly and belly to back and will do that to get somewhere rather than crawl 😩 what can I do to help her?
