Many people are afraid to touch the subject of racism maybe because the subject can trigger intense passions. I think it might be helpful to look at the subject from an analytical perspective.
There is historical racism in which blacks were occasionally killed for recreation. There was historical economic racism where blacks were encouraged to move from the south to provide cheap labor in northern factories. Ironically today many blacks encounter discrimination because illegals will work cheaper than they will.
There is even a new kind of racism. I knew a teacher who told me of a black girl that was put into a gifted class and her IQ was not even 100 (average). I asked if she was frustrated by not being able to do the work. I was told that she was not asked to do any work and she had a very high opinion of herself. If you consider the difficulty she would face in a work place that asked her to do work for which she was unprepared, you can image that she might feel her difficulty was because of employment racism instead of the educational racism that failed to challenge her to do the best she could.
Today the media and political activists get rewarded economically by making accusations that spread racial hatred. This is a type of social pollution and distortion of reality that makes them money, but harms those who come under its influence. If I think that the game is rigged against me, I may not even try to better my own situation and begin to seethe with bitterness against all who I have come to see as my oppressors.
If you encounter real racism, either confront it or move on to other situations. The race-baiters can harm you by making you think there is nothing you can do. Some will try to help you feel good by supporting the idea that you are helpless.
If I am in a car going somewhere and the car breaks down, I would rather get the car fixed than have everyone who passes by tell me it is someone else's fault my car is broken.
There are people who face a more difficult path in life, the unattractive, overweight, odd, and less intelligent. We have to do the best we can because the world was not designed to be fair.
You mention that you are doing better than you have in the past. You should give yourself full credit for your gains. Don't let those who would marginalize your accomplishments rob you of seeing a better future for yourself on the basis of what you have already accomplished.
