Advice on whether an internal wall is load bearing and necessary calculations

I am looking for some advice on whether the internal wall in my home is load bearing and if necessary calculations can be done to determine this. I am unsure of the specific material that the wall is made of- it could either be wood or brick - however, I do not have any structural drawings or plans for the building. Furthermore, the height and length of the wall is less than 10 feet. If possible, I am in need of an expert to assess the wall and help me determine whether it is load bearing and if so, conduct any necessary calculations.
