Which mobility aid would you recommend for someone who’s never used one?

I’ve posted many questions on here since I’ve joined but I have so many questions. Mobility aids are something I’ve tried to avoid. My symptoms are slowly getting worse and I’m constantly avoiding plans or having a hard time just getting up in the morning and I think I’d benefit from a mobility aid. I’m nervous about what people will think, especially at work! I’m thinking something small to pull out when I need it but when I’m at work I’m standing often and losing my balance very often so I’ve looked into rollators. I’m just not sure. Any input on what is helpful for you would be appreciated!
