I feel like I’m invisible to people and I don’t know how to deal with it

Hi I'm 17f, Lately I’ve been feeling really bad about myself because I rarely feel noticed by people in real life. People don’t really approach me or try to talk to me, and sometimes it feels like I’m just invisible. Even if I try i always get ignored or never get a good response

Most of the connections I do make are online. But even there, I have a lot of insecurity about my appearance. If someone asks me for a picture, I usually refuse because I’m scared they’ll see me and judge me or lose interest.

Then I end up feeling stuck. In real life, I don’t feel noticed, and online, my insecurity makes me afraid to let people see me properly. Sometimes I look at people around me who have lots of friends or relationships and wonder what is wrong with me

Now what to do and what if it stays like this forever
