how do you break out of a rut?

seems like things have been going ok, i just don't feel happy. i have a decent job that pays a liveable wage, am fairly active throughout the week either walking my dog or hitting the gym, and have a new gf who is really into me, although i'm not sure if i'm that into her. I'd been single for a while and thought I just wanted companionship, but now it feels like I'm settling. More and more recently, I have little motivation to do much and everything feels forced. is this just what adulthood is like? low sex drive, i just want to sleep all day on my off days, and my hobbies like video games, reading, and going to music shows just don't excite me anymore. am I just autistic? It feels like everyone and everything bothers me, and I want to be left alone, yet I crave some form of social interaction. Pretty much all of my friends have moved away, either to other cities or back to our hometown. Everyone else has their own lives, are married with children or whatever.

I hate feeling this way. I'm not suicidal but damn I hate being so negative all the time. It's become a chore to sit down and try to enjoy things I used to love.

get a full panel blood test, stop using the internet, and go to church

Find out what would you make you happy at this moment and do that. When you finish it, forget what you just did and go to the next best thing, and after you finish that, forget what you did and go to the next best thing. Keep repeating this and happiness will flow.

I won't read wishy-washy threads.

You have to force yourself.
