hi everyone,these days I'm feeling very low and sad for no reason. I feel like I have depression and I also took an online test for depression it showed moderately-depressed. but idk..i think maybe I am just overthinking about myself. sometimes I suddenly feel very tired for no reason, and I have lost interest in doing things which I loved to do before.., suddenly I lose my appetite or eat too less and sometimes I eat more or feel hungry too much.. idk what's happening to me, my parents are also tired of me, i haven't told them about this nor do I want to because I know they won't take any action, and I feel I might be another big burden on them..so I'm just dealing it by myself. I haven't told anyone in my family and i don't want to. Because of this I'm not able to focus on my studies..idk wht i should do, sometimes I feel like self-harming but I'm scared to do that also..pls help me.
