He has been ignoring me all day!!! Ugh :(

Should i be mad? I haven't seen him all day hes been at school and i asked him if he could help me do some of my homework before we settle in for the night! And he just gets annoyed that i even asked ugh seriously! Then normally after school he will text me and ask about my day but nothing today i get he may be tired or stressed but i still want to see him and i will see him tomorrow at work for like a hour but we never really speak for more than like 5 minutes at work
