Help i dont know if im overreacting

I feel like my boyfriend deserves someone better than me 😞 someone who is more beautiful and someone who are more responsible.

I been trying to find a job but I have no luck I tried a staffing agency but they always send me to temporary jobs. I feel like I’m not good enough I dont know if this is normal or what But I just wish i could be more stable😣 I fee like he deserves someone better than me.
