Just venting

Before some days I lost two childhood friends and it has make my mental health pretty bad beacuse im a very sensitive person.I dont really have many friends irl so since they left ive been pretty alone and ive been staying inside my house watching other people have fun and enjoy their teenage life unlike me.My parents think something is wrong with me beacuse i act like i dont care that i have no friends while on the other side I am not ok with not having friends and i feel like shit like i have no one to have fun with irl and i feel so jealous watching other people have fun with their friends.I try to make new friends but i just dont fit in and when i try i get anxiety and i end up getting embarassed.My parents also asked me to go to a therapist to see if something is wrong with me.Life is hard.
