At first, I saw that my mood had been low, and I thought of depression. Your question can be described in more detail so that others can understand what you are really confused about. Now the word "depression" sounds very general. Some diseases related to depression have depressed reactions. It may be a normal person, who is at a low ebb for some reason and appears to be depressed. It is also possible. Without friends, what can I say? Excluding some extreme areas, such as living in remote areas, you need to go out of the mountains. Or buy a mobile phone to facilitate contact with the outside world. If you live in a decent area and there are people around you, you still have no friends. Maybe it's because I'm too homebody, maybe I've experienced something, I'm too afraid to trust others, maybe I'm too passive. There are many reasons. Find the reason from yourself first. If it's really caused by your own factors, it will be much easier. Then practice and contact people. Make friends when you are still studying, make friends with colleagues who are easy to get along with at work, and in a certain place, you can also participate in activities organized by local organizations. Usually bring more sweets and snacks in your pocket, and you can give them to ta when you see someone you like. Smile more, care more about others, and look for topics of mutual interest. This can be brushed in good faith. You should take the initiative first, not afraid of failure. When you are brave enough, someone will always appreciate you. If it's not your fault, don't lose heart, read more books and enrich yourself. Spend more time alone. When your level improves, the quality of people you attract will be better. Friends are attracted. When you are good enough, good people will be attracted. Better people will be much better than those in previous circles. They know how to respect people more, love life more and are more real. We should look for the right circle instead of being belittled by the wrong people, who are always finding fault, right?
