friends ghosting me

recently i found out my friend just unfollowed my ig. he also left me on delivered for 3 days when I asked when he was coming back from his vacation. i deleted the message, but idk what I did. I literally did nothing, and he doesn’t like me. My other friend has also been talking to me less. I also did nothing to her. I asked when she can hangout and I have been on delivered for a day now, she always does this we used to talk so much and now honestly I feel like she was using me TIL she found other, prettier friends, it hurts. It hurts cuz I have been nothing but nice to these ppl and they just don’t like me for no reason, makes me feel worthless and depressed.idk what to do im scared everyone in my life will leave me, even my bf. advice pls?😭
