Do u ever feel like u wanna give up and walk away??

I love my boyfriend with all my heart but there are times I feel like what's the point or just to give up and walk out... I think I have insercuries issues and depression or something. Some days I'll be fine and then when I really get into that deep thought its like why do I do this for him ?? Idk maybe I'm a over thinker... 😳😳
