My fiancé feels like he is doing nothing with his life

He’s complaining that he’s doing nothing with his life. He works cleaning at a hospital right now with his mom. He is too tired to do anything when he gets home from work at night. And too tired when he wakes up. He has said he wants to open a store or make movies in the past. But he just feels like there is no one to help him. Like they say they will help him, but when the time comes they are just like “I don’t know what to do.” I tried telling him that he needs to think of when he did feel like he was doing something with his life, and try and get back into that. (This fall I was kind of going through a similar thing of feeling like I was wasting time and doing nothing with my life because I took a semester off school, so I’m going back again in the spring). He said that the only thing is he can’t do that thing because of his depression. I’m pretty sure he talking about wanting to be in the national guard at one point, but they wouldn’t let him because of all the anxiety and depression medicine he is on. I wish I could fix this for him and come up with some magical thing he could do with his life to give it more meaning. I’m hoping for some encouragement to give him or direction.
