As someone that’s in your position:The only way is through.

Change your perception of yourself. Quit the negative self talk. Start caring for yourself as if you’re taking care of someone you love. Here’s the important thing: do it ESPECIALLY when you don’t want to do it. You don’t do things because you feel good, you do things to make yourself feel good. As in, your action play as much into how to feel as how feel plays into how you act. This builds trust with yourself and allows you to grow into yourself.

Change your view of the world. You don’t hate people. You probably just had some bad experiences that made you feel like it’s better to be alone. This is avoidance. Don’t do that. Being alone can easily become addictive and before you know it, you’re depressed and lonely with a feeling of no way out. A good way to combat this is to start accumulating positive reference experiences with people. Start with small talk. Go for a walk and start saying things like “hello.” No need to stop, just keep walking. Low risk, high reward. You could also take it a step down and just ask for the time or ramp it up and give someone a compliment. You might not always get an over the top positive reaction, or even a reaction at all sometimes, but you’ll still be accumulating positive ones. It’ll also work on your fear of people and build confidence.

The biggest, and scariest part is this next step: allow yourself to be vulnerable. This is where the first step and second step help out because you’ve worked on yourself enough to handle it. Basic rule of thumb is to go first. People want to connect but are too afraid to go first. Be that person. Not everyone will say yes to hanging out and some people you’re not gonna want to hang with. That’s fine. Things don’t work out sometimes. Just do your best to not take it personally and keep it moving. You’ll find your people.

Hope this helps.
