Is it normal to hate being around people when your miserable?

Whenever I’m going through things I hate when my family invites me to things because they just make me feel worse. They always ask me a million questions stuff that I’m working on and struggling with. They brag about what they have going on. And they judge me for the temporary issues that I have. Like I been having health problems so I lost my loud speaking voice temporary and they leathery make weird faces to each other and laugh at me behind my back. They invited me to this party this Saturday and I really do not wanna go. I feel horrible for being this way. I do not feel like being judged and talked bad about once it’s over. I rather work and do something more comforting just to prove them wrong in the long run. Honesty everybody gets on my nerves even my friends I’m just not in the mood at all. The only thing that I care about is working and bettering myself. Please help??
