Felling like shit

Im felling like shit these couple of weeks bc ima little cry baby,my gf broke up with me and idk what to do,i always felt special around her,i thought a made her happy just like she made me happy,she was always worried about my health and mental health.
I did something wrong? I dont know,i think she broke up with me to be with someone else.

I thought that i was perfect,you said i was perfect.

Im not enough for you?Please tell me.Im so scared to lose you.
