Struggling with Depression and Relationship Insecurities

I struggle with anxiety and depression. I'm not sure whether it's the anxiety that causes the depression or the other way around. Needless to say I struggle with knowing myself and just feeling real/feeling anything a lot of the time anymore. I've been with my boyfriend for 2 years and I've made mistakes because I'd get in my head too much and convince myself I dont deserve him and although I love and care for him, I feel empty and like I dont deserve him or that im not worthy of the love I do recieve from him or anyone. He'd literally do anything for me and I would for him as well, that has been and always will he the case regardless of what happens. Because he's forgiven me so much and loves me even considering my mistakes, I feel the same way you do... Like I rely on him too much and like I literalt can't live without him. I'm not sure if it's normal or healthy, but I completely relate. Maybe it's a trauma bond or maybe us as people just cling to any thing/person that we know that cares for us and that brings us joy because on other days we dont feel much at all. My love and prayers go out to you, were all human <3 if you'd like to talk message me ! :)
