Random vent

I really dont know what to say or do but i feel like my girlfriend is getting distant from me for no reason.. i have alway been a kind person, im trying my best, i have never been mean to her, not even as a joke. But it just happened. Out of nowhere. Im tired too, i just want to talk with her even for fuve minutes, im trying to give hef my whole time in my life and she can't even tell me how she is doide so that i know she is fine and that i dont have to worry. I don’t know what i did to deserve this honestly, and im starting school soon too, im not okay with my mental health, im losing myself completely
