Crying wolf or a matter of this line of work?

I am a junior M&A and securities associate. Many partners and senior associates I work with often see very tight timelines and say the client wants to close next week or ASAP, only for work to be jammed on me then deal doesn’t close for another month or term sheet not even finalized or died. Is this reasonable and expected or is this more about my firm and my firms culture? It is mentally exhausting and draining to prepare all documents and then term sheet suddenly changes and have to redo everything, or to gun-up for “closing” for the deal to not move for 3 weeks. Everyone wants to be the only deal you work for and expect you to work on a deal as if it is your only deal but this is very draining.
