Younger masc lesbians, do older straight women tend to treat you poorly?

I’m 23 and since starting a new job I’m realizing that throughout my life older straight women tend to not like me from the get go. My entire social circle is girls my age of all sexualities, one of my best friends is a straight woman and at events of all kinds or when I was at university I got on with straight girls no problem, but when it comes to the workplace or older social circles I find myself almost being bullied by older women and end up falling in with the men (I’ve very much never been a ‘one of the boys’ type of girl) just to have people to talk to because I end up feeling very left out. I really have no idea why this could be and the only reason I’ve thought it’s related to how I present myself is because girls my age who are feminine presenting in the same circles will be accepted fine, plus the fact I’m from quite a catholic and isolated town, but maybe I’m overthinking it.

I really thought I was making it up until I started my new job at a large company but genuinely from day 1 I’ve had one-sided problems with older women while older men have been very kind, almost the complete opposite experience of social circles my age which has been very confusing. I’ve noticed it in other part-time jobs too, even with customers. I try not to let it get me down but after 3 months of everything I do being chastised or just being constantly ignored I find myself left thinking if I’ve done something wrong or said something wrong to make them not like me and it can feel very high-schooly which gets me down. Even when girls my age start I’ll be talking to them fine but they’ll fall into groups of women who seem to want very little to do with me.

I’m planning to go into healthcare so if there’s anything I could be doing differently I’d want to know considering a lot of patients and co-workers will be older women and I do want to be able to form friendships with them, there’s only so much male company I can take as kind as they can be lol
