had a terrible day, feel like everything is just going away and am extremely sad. everything is falling apart

I have hold back my tears . I’m trying so hard to play it off. I can’t think about it anything without on the verge of falling apart . I have no self control over my mind . I’m scared. Is this a psychosis . I have barely eaten in days . My stomach is growling but I have no appetite. Idk what’s going on . Normally if I have a rough week I can fight it but I can’t fight it this time. My biggest fear is loosing my bf. I’m spending the day with him and all I can do it think about what’s gonna happen when I leave .

Last week was a lot easier for me. I felt like thoughts didn’t control me and my actions as much as they did earlier. Today was really hard for me and I feel like I’m starting to lose hope again:( I can’t take the thoughts and the feelings that come with them anymore. I feel like I have failed and I’m never going to be happy again.

All my real events are hitting me all at once and i genuinely despise my existence right now... i feel so alone and genuinely horrible and nothing is working for me right now... im trying to not ask for reassurance but its so dang tough and i dont know what to do... please someone help me... i feel so so so so so alone right now...
