It sounds like your LO has gas problems as well as is maybe over tired.
For the gas try Oval. It worked really well for my LO. If it doesn't work for you talk to your DR or phamasist and they can recomend other treatments.
It also sounds like she might be useing you a soother. Have you you tried to give her a paci? If you deside to do it try to find one thats similar to your breast and it'll be easier for your LO.
Now for your sleep at night something I used alone with the EASY routine;
Swaddle your LO, place them on there side facing you, give her a soother, swing her by rocking, and shhhhh to her (or sing softly just enough so she hears your voice) Make sure when you lay her down facing you she isn't in front of the breast, and a BF baby she'll try to latch if she's to close nd you don't want that. You don't want to be the soother.
Once you have her calmed down try laying her back down. Sometimes it can take a while but with a bit of persistence and patience it'll worrk.
This was how I did PUPD (pick up put down) for my LO it was the best way for me to cut of the outside stimulation and help her settle herself. It also helps to make there tummies more comfortable when they're on there side. By putting them down when they calm it helps them to learn to sleep on there own.
I'd recomend you try instating a routine for your LO right away and you'll hopfully see a difference soon.
Its really hard having a colicy baby but with a lot of love, some persistence, and some patients you'll do fine.
Be encoraged that your doing the best that you can do.
Doing the this when your LO is gassy, really builds a strong bond, and trust for your LO who learns that you are there for them.
After a while you'll find that you no longer have to do this, and you have a stronger happier baby.
