I need your guys’ help

I’ve been struggling with my mental health a lot more lately. I struggle with opening up. I’m a bottle it up kind of person and it’s making me feel worse every days. I went through a lot this past month and I’ve tried opening up to a friend and it’s just too hard. He gets frustrated that I say I’m struggle, I want to change, he gives me advice on how it’ll benefit me if I change, yet I don’t change. I know he went through a lot before and he was able to change but it’s just not the same. I want to take his advice and change for my health and well-being but I don’t know what to do. Can you guys help ya girl out and tell me different ways the I can improve myself and change. My mental health went from anxiety to depression. I tried avoiding it but I let myself get into that hole and now I need help to get me out of this hole. I want to change not just for myself but for those around me. I don’t want it to affect those that I love. Help...please...Im desperate...
