What’s wrong with me

I don’t know what’s wrong with myself I’m happy and sad I wanna eat sm but then I don’t wanna eat at all I feel alone in this world I have a boyfriend but I fear I can’t explain this feeling anymore I feel empty sometimes not like out of love but me in general like just plane number and boring I feel like I just no longer wanna walk around but I do it’s so odd I don’t know what’s wrong I wish i could speak up but sometimes I just shut myself down cause I don’t wanna be a attention seeker or something it’s hard.
