You could choose a different distribution for what you are sampling from. It's possible to sample from a lognormal distribution instead of a normal distribution. The lognormal has the structure of having a non-negative support. I think if you use a normal distribution it may simplify the derivations of certain expressions (like error propagation). There are resources out there for you to use that can explain how to do so and what CI's or standard errors look like for a lognormal distribution. A lot of these might be in the health field as the lognormal distribution is really popular in pharmaceutical/clinical trials research for some reason.
