I FEEL FUCKING SICK

I just wanted to vent. You're welcome to read this or simply ignore it. 

Two things have me feeling anxious/super sad. First, one of my friends in my group (there are six of us) confessed that she started dating the guy I liked months ago. It really hurt; I'd had a crush on him for a year. Of course, he never reciprocated my feelings and even told me I disgusted him (I know, I'm such an idiot). In December, I broke down and told my group how much it hurt to have my feelings unrequited. But I got over it, or at least I'm trying to. We'll call this friend Sushi. She told me she didn't want to say anything before because she knew everything I just said. I told her it was okay, even though I was actually crying for a good while.

 Secondly, a friend from the same group—let's call her Raspberry—said in our group chat that she was feeling sad. (I love giving emotional support since I never had it before, and I'm also the oldest in the group; I'm 19 and they're 16 or 17.) She told me that one of her friends, who is really close to her, basically wants to leave and not take her with her. I was a little confused at first, then she explained better. Basically, it seems that this other friend of Raspberry wants to distance herself from her and her other friends (she sent me screenshots of their conversation). I gave her advice with all the wisdom that my 19 hard years give me. The thing is, this friend she's talking about could be one of our friends in the group, let's call her Pizza. I think it's Pizza because a couple of months ago she said she didn't feel comfortable with our group of friends, and kind of lacked trust. Maybe it's someone else, and I'm just overthinking it, but something tells me it's Pizza, and I love Pizza so much. I consider her a true friend, and I would hate for her to leave. It could even affect our group of six, and I don't want that. I never really had any friends until them, and that's what hurts the most—being alone again. I've been crying about all of this. Ugh, I just want to escape (plus, it's exam week, and I'm struggling in some subjects). Anyway, thanks for your attention. Bye.
