Architecture - Load Bearing Wall Question

Hello all. Owner of a 1 1/2 story Cape Cod home. Have just about completed a master bedroom renovation for the home and am faced with a final question. I have a door and stairs situated in the middle of my first floor that is pretty tight to a linen closet and the door is somewhat small. Looking to get furniture up there may be a bit of a challenge. Have an idea which may rectify but would like some advice if possible. Looking to remove a short wall next to the stairs which I could then put a railing up. This would allow more room for access and moving items. Need to figure if it is load bearing though. I will draw a VERY crude diagram below with THE "O" symbol representing the wall. It runs parallel with joists so think it might be safe to cut, but I know that isn't always a good rule.

UPPER FLOOR JOISTS RUN North/South, Lower Floor Joists run East/West

Thanks in advance for any commentary.

Looks like the original post did not hold the format I put everything in so in essence the email is non-sensical. I will attempt to put together something that can more easily be seen. I have no URL to post a picture of so I will try and think of something else.

Thanks in advance.

The only way to assure that a wall is load bearing or not is to have a structural engineer inspect it. Then, it's even difficult. Sometimes a savvy building inspector can advise. It is best to call a structural engineer. No one can really tell by looking or advise you based on a description.
