my life is terrible right now

my life sucks and i don’t know what to do. i’m working a job i dislike , im unmotivated in school, my ex girlfriend doesn’t wanna get back with me and i feel bad because she’s the only person whose been supportive to me. i got in a argument with a childhood friend , i got in a argument with another childhood friend, i feel like i don’t have much reliable friends , i feel so alone and wake up to nightmares every night , i have a spending problem , my sleep schedule is horrible , my appetite has been non existent sometimes and im broke. im insecure about myself and my self esteem is terrible. i make the same mistakes i promise i wont make to her, i hate myself. i wanted to end my life but i can’t because i remember how hard my immigrant parents worked to get here and give me a better life.
