Thank you all for your kind comments and advice! I feel like such a weight has been lifted from my shoulders knowing that I'm not alone.
I was trying so hard to help support and look after her mental health that I never realized that it is her own responsibility to make a change in her own life.
Thank you all for helping open my eyes to the reality of my situation and giving me the encouragement I needed to finally stand up for myself.
I wish you all the best and blessings to you all!
