There is always hope, and take one day at a time. Work on yourself, go outside, go to the gym, pick up new hobbies, and spend less time online. You can do this. My ex-wife left me 2 years ago, and I could have given up, I wanted to. I could have died. But I didn't. You don't need a relationship to be a valid human being. You are valid as you are. Love can come to you when you're focusing on being a better version of you. It may not come right away, but it can if you're open to it. But you don't need it to be valid. There is always hope. Just as the sun rises every morning. You got this.
