Hi,
Four daughters (3 elder sisters and youngest child), aging parents (father is weak, mother probably has some eccentricities and limited attachment) and limited family support will probably summarize the situation better. Weak mind unable to manage stress, could succumb to pressure and take hasty decision. So, please consider strengthening your mind. Better days will dawn… life will be a bit difficult, but there is light at the end of the tunnel.
Take care…
