Three main conditions you may find yourself in
1: Actually happy
2: Sad, upset, frustrated or a negative emotion in general but pretending that everything is ok (not venting)
3: Negative emotion and venting
Possible responses that you may get:
1: You deserve the happiness that you have (e.g. "you worked hard to get this, you deserve it!")
2: You deserve the negative emotions that you have (e.g. "you're so lazy, it's no wonder you're poor. You're a useless eater, a leech who contributes nothing to society", or "trans people have high suicide rates, therefore it's bad to be trans", or "it's your fault you have no friends and no partner. you're ugly, you're a loser, nobody wants you!", e.g. how the media depicts "incels", or some people's attitudes towards poor or homeless people, tending to blaming them for their situation, or people who point out that transgender people have high suicide rates, subtly (or not so subtly) implying that transgender people are bad, or expressing some sort of Schadenfreude and saying they deserve that situation, instead of acknowledging societal hostility).
3: You don't deserve the happiness that you have (e.g. "you're privileged!" (said with a negative connotation), "you don't understand the pain that comes with being marginalized!" etc.)
4: You don't deserve the negative emotions that you have (e.g. "you're a good person", "I feel so sorry for you, I wish I could help/I will help!", "people are so ignorant and superficial...", etc. answer based on empathy)".
Because all four combinations are possible, no matter if you're actually happy, or sad/frustrated but pretend to be happy, or openly sad/frustrated and venting (perhaps seeking for sympathy), someone who plays "dirty" emotional/conceptual games will always frame things against you. There's no "winning" stategy if you play by other people's rules. The only winning move is to always play by your own rules.
