It's OK to feel frustrated, even a little bit trapped, because you are, a bit, for a while. Crying is also OK at a time like this! But you'll be getting some help, and that's huge.
Different people are wired differently for dealing with adversity. I can't advise you on technique - I will say that making your rest and recovery a priority can be challenging when there are others to consider. You know that, but it probably helps to be validated
