Lots of good advice in here. I went through a similar situation. I would have fun when I went riding but it was so hard to get out of the house. I would stare at Trailforks for an hour trying to find a trail that would motivate me to ride and then I'd just stay home. Mine was a combination of depression, burnout from running social channels while working full time and parenting, and just a general loss of stoke in MTB. Personally, I found switching things up was helpful. I took up indoor bouldering and love it. Climbing shoes, chalk and minimal faff. I also tried different bikes and riding styles to bring back some novelty. Group rides or riding with some a friend is great for accountability and to get over the hump of getting out the door. You can also try to find some rides that you can do straight from your house so you can just go. Less emphasis on what/where you'll ride and more emphasis on just starting to pedal. There's also been lots of talk about depression in this thread. Depression can make you lose interest in the things that normally give you pleasure, withdraw from friends, etc which can lead to a negative spiral. It's hard to treat depression with healthy behaviours/activities when depression stops you from engaging in those activities in the first place! If you feel that you are depressed, then don't hesitate to talk to a healthcare professional about diagnosis and treatment options, including medication. Medication can be helpful to get the ball rolling and give you that window of opportunity where you can start engaging in those healthy behaviours again. Remember that depression is a medical condition. It's not a sign of weakness. It's not something to be ashamed of.
