I like being alone. I know it's impossible. I still can't help thinking of him. I always want to send him a message. What should I do?

What to do specifically, or ask yourself what you want:

1, you can cling to the past and even worry about it, so you can only live in torture and contradiction;

2. You can also put it all down and enrich it with work or other hobbies;

3. You can also open your heart again, make new friends and appreciate new feelings.

What you choose depends on yourself. It takes courage to start over, but the front is your right choice. When you walk past today and look back at yesterday, everything is just the scenery of the past. As long as you persist, you will have a bright future.
