Fussy phase ??? Growing pains

Does anyone’s 2 almost 3 month old just want to use the boob as a pacifier all the time. She is exclusively breast fed and

Wakes up all through out the night

Just wondering if this is a phase or if there is something I may not be doing.

She won’t nap and if she does she falls asleep on the boob and will wake up instantly if I move.

I went back to work 2 weeks ago so I think maybe she just wants to be close to me. She has been fussy on and off and I thought she had some gas. She has also started drooling a bunch so I thought she may be teething. Not sure what I’m looking for maybe just venting or some advice on if this is normal I am a first time mom.
