Hi CarmenKate
Being transgender requires patience, lots of it, and the strength to see things through, especially when you feel insecure and are having a bad day. And feeling insecure is something which virtually all women feel at times about their physical presentation, so you're kind of in good company here

Your friend was being honest, which is a good and bad thing, but you're only 3 months into HRT, so let it do its work. And later, if you believe it would help, you could consider FFS. But frankly, it's too soon for that.
The issue of people still seeing you in your former gender can be hard for some people, but it becomes easier as you become more feminine in all dimensions. That's another area where you should be patient. And of course, it's important to surround yourself with kind and positive people.
Hugs
Julia
