importance of QT

So, I'm still doing my best to spend some quiet time with God everyday in the morning and boy what a difference it makes. When I do it I can feel God's presence, love and peace from His benevolence. My days are relatively clear on what I need to do and life seems to have purpose. When I forget or somehow just don't spend time with Him (especially a few days in a row) I get more depressed, feel like I'm doing nothing with my life and going nowhere, hate myself as stupid and spoiled and end up drinking and drugging more. And of course the more I do them the more the cycle of suffering spins with hangovers and withdrawals. Truly if I am to get through life it is only by God's grace and spending time with Him through Jesus. My pastor also told me and my brother to read passages like Isaiah 49:9- together and decree them over me to believe and declare that God will heal and free me from my issues and lead me to help others too. She keeps saying I'm beautiful and will be specially powerful in the Holy Spirit which is jarring for me to hear from a relative stranger and considering all my mental health problems. But I do believe God can heal anything and anyone. Even as I spend more time with Him I notice that my borderline personality tendencies go down. I just can't freak out about things as much. And then it's shocking how unstable my normal state is when I don't spend time with Him. On Friday I felt like there was no point to my life and living when we left late to go have supper before service with everyone. Sounds ridiculous but that's how far it goes when I get stressed since I'm hypersensitive. But when I have the peace that transcends all understanding I don't get that stressed in the first place over small things.
