Welp ... I'm depressed.

So about 2 months ago my 2 closest friends of 4 years stopped talking to me and I dont have any closure so I'm wondering if I did anything wrong. I've reached out and was ignored. Called fake by some of out mutual friends. And from there everything has gotten worse. I feel like I'm worthless. That theres no end to this. That I'm drowning in my own sadness. My boyfriend helps in anyway he can but I feel like I'm a burden to him. I was supposed to get teeth taken out but I got scared and my parents told me they were highly disapointed in me. I dont know what to do anymore. 😔
