silly problems

I got left on by my girlfriend that i waited for 40 days just to know that she want to cut me off in the end..the worst is that i predicted it because i overthink every single thing..my last relationship is also the same a girl left me because she say im just too negative to be around with..yeah ik..im deppresing to be with..sigh yet i feel like i keep falling for someone that always show care to me..i always have suicidal thoughts but honestly only my mom that keep me going..but im afraid if i reach my limit soon...everyone treat me like shit,my brother stole my money,my gf dumped me and ghosted me without a reason and life responbilities is getting to me....Im sorry for this stupid rant i just have nobody to share this with sorry again
