I turn to God. I still feel sad that people in general aren’t interested in being friends with me, but it’s okay these days because the Lord is my comfort.
You are not alone in this. No one is interested in being friends with me either, but then I’m very discerning in who I’d want as a friend. @Colonelmustardseed
Distractions. Long term distractions. Hobbies with other people are usually the best, or something that really imerses you, like games, movies, fishing, or even fish, reptiles and snakes.
Close friendships can help, but i feel like this one is a double edged sword, because if you're lonely and you get attached, once they're busy or not around it can be really hard. :(
I’ve had this feeling most of my life, so know that even if it doesn’t feel good, you can live with it, and survive, although survival mode is not really living, but it’s still doable.
I can only share my own experience of how this feeling went away. The first time I felt truly loved is when I felt a great inner peace and contentment. I was 25-years old, and it was the first time I’d felt it. It lasted less than one year because the one who gave me such love passed away. I have never felt that kind of contentment since, but I’ve had days or even weeks, where because my mind was engaged in something very interesting to me, or I was giving and receiving love to my pets, the emptiness went away for short periods of time, so for me, it was love ... giving and receiving, and feeling like you matter, mental stimulation that’s of great interest to me, and the company of the right people.
First off attitude. No, not as you might be thinking about attitude. Yet more like outlook.
You got to want to change, really change, first!
Without it, nothing will help. Even if you are a believer. Belief means outlook as well. That feeling of emptiness will always be with you without a change in attitude.
Once you have the attitude settled, then any of the suggestions here could help. Yet attitude comes first. Without really wanting something better, no one can help. It's the degree that you want something better. Not just saying so.
Apathy (saying you can't) is your worst enemy BTW.
Work to the point of total exhaustion where you don't have time and energy to feel anyhow. Also, if you get some success, it brings feelings of satisfaction.
Get hobbies. You are very young and have enough time to learn new things. Get some entertainment, read books, get pets if you can. Listen to music. Do whatever you like. But don't let yourself down by thinking you are alone. 🙂
Listen to podcasts about things that interest you (I find listening to another voice soothing).
Keep yourself busy with hobbies that you're very passionate about.
Try to spend more time with friends or at social events.
Also, I think just accepting those feelings of loneliness, that you're just feeling that way right now, can be helpful. I like to accept that some days, I will just feeling shitty. Anxious, angry, on-edge, teary... etc. And just accepting it makes it easier to bear over time, if that makes sense?
Need to find interests you can become passionate about. Seek out others by joining a club or group with similar interests. Being on here helps too. Chat to others, post stories to help get things out of your mind. It really helps writing stuff down.
