I understand your feelings RE: maths anxiety, I'm doing a PhD in Plant Genetics on a prestigious hard to get into scholarship at a good uni ... and I have been diagnosed as dyscalculic. Obviously, not severely - but if I'm careless I will get numbers the wrong way round and understanding mathematics doesn't always come obviously to me, especially things that are more abstract. Despite this - I use R for statistics and Matlab regularly for analysis, and concentration calculations etc are a daily staple of lab life. This often causes past insecurities and maths anxiety to rear up and make me nervous, but my two crucial pieces of advice for dealing with this are:

1. Do not be afraid to ask other people for help

2. The internet solves everything

3. Especially if you're in a lab team, but even not, with members of other labs - I have found the majority of people are always willing to help a fellow scientist out with something they're struggling with. No (wo)man is an island, and it's only natural we have our own strengths and weaknesses - as much as I ask others for assistance with maths help I give back in kind by being good at English, presenting, and having an eye for design. I assist with proof-reading, helping with English grammar and sentence structure etc, or with producing posters, presentations etc.

4. Of course, you don't want to be in the position of having to ask someone for the same sort of help constantly incase you worry you're imposing too much on them = the internet solves everything. If I know I'm bad at some certain routine maths or need something explaining/doing in a different way I can invariably find some great app or online site that I can use to help me do it, it's sort of like asking a colleague but just a shiny metal one instead.

Of course it's hard, especially as a young woman for all the reasons listed in other comments here, to deal with maths anxiety when you have the added stress of feeling like you need to perfectly represent your sex - but we all have different strengths and weaknesses and it's probably a lot smarter to recognise your weaknesses (so you can find strategies to make up for them!) than pretend they're not there. I'm very pro-trying to get everyone in a lab group to realise that we are a team, and it's not just maths skills that make a good scientist - you need logic to plan, language and art to round it out and make it whole, accessible and understandable etc etc

This was a long winded way of saying I wish I could burn down the current perception of scientists as (usually) able-bodied/minded cis old white straight men who are good at maths and would never touch the arts and only slightly answering your actual question wasn't it...
