This is a really normal worry for the large majority of rabbit owners! I think considering who else may accompany you is a great option.
Does your rabbit squirm a lot, and this adds to the anxiety? One thing could be de-sensitizing your rabbit to touching her paws (don’t try to clip them, just touch them and look at the nails, like you would to cut them). This may calm her down over time, and may help you gain confidence in the motions. Doing this while getting help from an outside source to actually clip in the meantime may help you be able to do it independently long-term; but there’s nothing wrong with having someone else who is experienced do it. It definitely isn’t an easy thing anyone can do after just a try or two.
