24 and everyone is leaving me. My sister is getting 18, dad moved away, mom is getting older, grandparents are losing their minds from aging

My mother and sister came to get documents and luggage for there. It broke my heart and my stomach. My father abandoning me I developed c-ptsd, now my sister abandoning me, I will take to do some bpd and jinx left by vi-core depression. Ah, I hate my psychology degrees. And if anything happens to my mother, from age or drinking, I'll just follow her at best. Why am I so bad?
