By what you typed you are aware that he obviously thinks you're weak because of your anxiety and to be honest why would you bother sharing any intimate side of yourself with someone like this.
If you can handle it, then that's fine but if not; they will probably drain you , throwing a negative spot-light on your vulnerabilities just to make them feel in control. This is usually because they don't have the gumption to deal with their own feelings and think they are flawless.
From my own experience of partners who are like this, they are generally either ignorant/immature/just plain bad. They may provoke you to confront them and cause drama so that they can scapegoat you. They may want to have the last word and enjoy controlling you. Or they simply may have no understanding of your condition. If it is the last point, then maybe he can learn to understand but if he isn't empathetic, then this is a fruitless exercise.
I obviously cannot say that this is what is happening with any certainty but there is usually a dynamic when you are in relationships with ignorant people/control freaks/manipulators - it is one where you will always be carrying their mistreatment and end up feeling weak, because that's how they judge you. You will end up blaming each other over and over.
Being constructively critical is one thing, it requires emotional intelligence. If he is not being sensitive to your needs, especially when you have EXPLAINED them to him this is simply NOT good enough.
I hope he has the willingness to be open to respecting you for who you are and support as well as understand you; helping to 'build you up' instead of the opposite. If not, or if he just thinks you are 'over-reacting' I would seriously consider ending it - it is not a good portent of things to come. Relationships and life are difficult enough, as is, without this not being the default mode a couple should strive for.
Err on the side of caution and don't make excuses for your bf's lack of empathy.
