I am naturally a very shy person, I find it hard to get people to take me seriously and make get my point across well. This can be very challenging and sometimes leads to people taking advantage of me and "walking all over me".

Not only am I quite shy, I find it very difficult to tell people if I am unhappy with something or if I think they are treating me unfairly . I think it's possibly also to do with the way I look, I am quite small (5ft 3) and look younger than my age, my voice is also very small and honestly kind of squeaky. I'd like it if you could give me some advice on how to become more assertive without coming across as arrogant or self righteous but also without putting on an act (for example, I can't change my voice) Thank you!
