Depression, Stress and anxiety and loss of my ex boyfriend that was murdered by his supposedly best friend 
I know it might seem a bit direct, but before anything else… what about you? Are you safe? Are you okay?
I am so sorry for the things that have happened in your life I know it’s hard every day your here you are getting stronger you are a blessing believe it believe in yourself keep going things change you won’t forget but things will feel lighter that’s how you can start filling yourself up with love and to live 
Oh no, that's not good I am so sorry. Drinking/using can only make it worse, right?
Let God do his work, talk positive people, and keep the faith. Take care of yourself most importantly. You matter.
