How long has it been? It can’t not be hard at first. But if you try hard enough you’ll learn to be comfortable with yourself and be alone. Finding hobbies does help for sure, particularly those that involve people.
You could try yoga too, starting from scratch is a great place to begin. It’s a great tool to learn to see yourself objectively and be able to let external things affect you less. (I’ve been practicing for 10ish years and teaching for 5ish) Also yoga communities are usually great because it’s mostly people trying to actively improve themselves. But do go for the dynamic style if you try it, because it builds the mind but also the body. So even if you don’t get into the spiritual stuff, you always get a good workout.
Best of luck. Hope you can find the strength to embrace the pain and not flee or hide from it, because it truly makes us stronger.
