Dear Aquarella,
I think you are going in the wrong direction in finding the reasons for being sirred.. It's completely those A-holes around you...
First of all, now build your self confidence,,.. watch an inspirational movie may be.. ha watch,,, legally blonde 1 and 2..they are funny too.... or do anything else that will work for you...
Now remember, the term "transsexual" is just a word that was created by some entity in the field of science to identify a group that they assumed as completely different from the norms of gender... In the reality, we are female no matter what our labels may sound like. In fact, think as there are only two kind of sexes\genders in the world,, name them as you want... like A and B..
So now the problem is B people are not accepting the fact that you are an "A" person. if you really feel that you need to be accepted, don't feel down like this. Be tactful, effective and strong. Instead of going through make-up tutorials go and read some stuff about effective communication skills and how to build verbal and non-verbal skills of a strong appealing personality.
If the problem is at work. lets say if both your superiors and equals are doing what they do now, start with the superiors, tell very politely and effectively that you do not prefer being assumed as a "male" and that is a right of yours. Don't show non-verbal cues of desperation and depression, show cues of control, authority and power. As for other A-holes, isolate the bastard No.1, say something well constructed to intimidate him in front of all or few. first simply tell him and them that you don't like to be taken as a male, as a request. Surely, they won't listen, then take that Bastard no.1, and hit him harder. Without showing anger or desperation, directly tell him that you will not tolerate his stupidity. Hit him hard as you can with well constructed words. Question him, tell how uneducated he sounds like, Ignore what ever the ->-bleeped-<- he will say, stick to the goal of putting him down or to make him extremely pissed and yet you stand strong and polite proving your point of his low mentality. just stick to your point and win that situation as a strong "A".
Trust me this will work... Put down the pack leader,,, then all will fall...all my life I had been fighting for people who were being bullied by others. I always choose the strongest to fight with... and I made sure that I won........
Just try to install your power and spread some sort of a fear and let it grow, ok,, the fear I am talking about here is, the fear of people to be taken as stupid, or to be intimidated, or to be taken as an inhuman and most of all the fear of you as someone not to be played with. Do it once properly and it will grow like a tree. Remember you are dealing with people who are way below any beast. Just fight effectively.. master the needed communication and leadership skills first.. eye contacts, posture, gesture and all those are important... Don't ever run my dear...
ok.. ill stop now... damn sleepy..
