What is wrong with me

I feel so numb about everything in life and not sure why I’ve been feeling like this for some time but worse now. I’m 36 and have everything most people my age want I’m married with kids have a good job own a home yet I feel I guess empty ? I don’t have many interests, I don’t have many friends now I juts don’t care to be around people. I find most people fake, annoying, self- absorbed, obsessed with social media. So hard for me to actually like someone and want to be around them. I used to be fun, outgoing had lots of friends now I’m a loner, I juts want to be at home , i juts feel so blah I feel like I don’t have anything t say even when I’m with my husband we don’t say much . Not sure what would make me happy i feel like I’m just there if that makes sense does anyone else feel like this or felt this way? How did you snap out of it?
