I feeling I failed the mother job

My LO is almost 10 weeks , I have had hear baby growing more they are getting a bit easy, but my LO is not ! She is getting worse and worse.... her sleeping , feeding, all of that not going well. I still have to held her all day to make she happy I remember when she was newborn, held her at sit in couch should be fine but now I need to hold her walking around the house , if not she will being fussy or cry. Before feed her one bottle formula only took about 15-20 mins to finish but now she fell asleep every time , I have to change her diaper or clothes to wake her up but usually take me 40 mins to feed one bottle. I tried changed the nipple size , changed bottle all nothing is help, always fell asleep couldn't finish whole bottle so she wake up in 2 hours cry to asking to eat! She having acid reflux and colic so she is not always happy baby, crying a lot during 7pm-12am every day , we tried every thing to make she can sleeping better but she just can't clam even held her walking around, listen music, take her bath etc....she just cry cry cry then get tired and pass out around midnight ..... I feeling so tried everyday and so scared the night is coming cause her crying , I can't help her clam and being happy ....
