- You're doing this to yourself, buddy. There's always more work to be done; it's not your responsibility to do all of it.
- You're not going to outrun a train by running faster on the same railroad tracks.
- When (not if, but when) you finally crack up, you won't get a word of thanks for your efforts. They'll just ease you out of the company (gently or, more likely, not) and hire someone else to replace you.
My advice is:
- Gradually start padding your estimates until your work fits into a 40 hour week.
- Learn to say "no" or at least "not right now" to requests from other people and other teams.
- If you get dinged by your management chain for reducing your pace, find a new employer ASAP. Good managers want their employees to work at a sustainable pace because replacing good employees is expensive and risky. You clearly don't have good managers.
I'd add to this good answer, that I'm afraid, padding estimates gradually won't work — you are already working nights and weekends, and the worst — seems like you are expected to.
I worked in a similar environment for some time where I was expected to start my morning at 7am by joining a call with an offshore team and end my day at 11pm jumping on another status call. I could not fix it, this state of operations was enforced by management.
So many things are wrong here that I just don't believe you can change anything there either, you gotta find another job in my opinion.
For the sake of argument, let's assume you try 10 different strategies over the next 6 months and all of them fail to reduce the overload. Will you still feel responsibility for not being able to keep up?
A lot of people don't recognize that sometimes you can't fix a situation and that isn't your fault. Burnout comes from that - lots of effort with no result. A great sign of this is that the company has hired more people and the workload increases to keep everybody overloaded.
As ThrowawayR2 said, don't enable this behavior and take responsibility for working nights. Push back against requests and work a sane amount of hours. Make it clear to your management that the workload isn't sustainable. Do this so when you look back you don't ask yourself "Should I have been more clear with management? Was I the problem?" If that isn't supported then find another job.
