Anyone else not feel strong enough for this world?

Anytime anything gets difficult for me, I seriously just break down. I have anxiety and depression and I feel like it’s just out of control. I’m 21 years old, still don’t know what I want to do with my life and my boyfriend has it all together, which makes it even harder. He doesn’t understand mental illness, lucky him. I just wish I had it together. I feel like I’m just weak & not strong enough to get through this life. Im 21 & already feeling like this..that’s scary. Anyone have any motivational words? ❤️
