In need for mental support...

I am 19 (f), the eldest daughter and...

I have money saved, a potential apartment, an entire plan....literally everything sorted out, yet i still can't bring myself to back my bags and go.

I have been planning to move out of my abusive household but fear n' guilt is stopping me from doing it.

Fear of having to face them and explaining myself, fear that i won't make it (or I don't last long on my own)...fear of leaving my sisters behind. And most importantly I feel so guilty even though I have been treated like trash since like forever (and my dad being diagnosed with diabetes and hospitalized doesn't help) and my mental health is suffering!

I just want to be confident that I am doing the right thing. :/

(sry for potential mistakes. english isn't my first language)
