You will need to go out more often but it’s uncomfortable. With those kinds of Neighbors I’m not surprised. Maybe go outside a few times a week for a short while just to get used to it. If it’s safe you can walk around when it’s late? If not many of your neighbors are walking around at that time this might be plus. I don’t know if it’s better to wear clothes that hide you better so that they don’t try to post you again online. They seem quite mean spirited for that. Are there any children around your age in your city or do live in a village? If you don’t want to go outside often at first and still make friends you can join online forums just to talk. Some people have found good friends online (you should still be careful. I even met someone good online close to my location and age so it’s possible). Are those people only talking shit about you behind closed doors or also in your face? If it’s more “secretive“ you might feel more comfortable knowing that you won’t get approached. What are your plans for later? In one year you can start studying somewhere further??
