Depressed ?

A couple days ago I & my boyfriend broke up & we’re both on a trip together but we aren’t speaking to each other just a lot of eye contact & looking away . But these last couple of days I haven’t been eating , been really over thinking a lot of stuff to the point that I can’t sleep , very angry sad snd stressed & not much talking . I’m good at hiding my emotions around my friends but I’m really falling apart. Idk if I’m starting to go into depression but I feel like it with the lack of appetite & wanting to be alone . I really don’t know how to cope ..
