How to pray for focus and guidance?

I've been feeling down for a while due to a lot of different things, and I find it difficult to stay focused and get things done. Part of it may be due to laziness and procrastination, but I think it also has to do with my mental state and feeling down most of the time. I'm unemployed and back at uni, and although I have a lower workload, I'm finding it more difficult to get things done. The only thing I have managed to stay more or less consistent with is praying every day. I pray a full rosary, dedicating a decade to different people/causes, and I pray to Jesus, the Holy Spirit, and ask Mother Mary to intercede for me. I need help focusing and finding the right career path for me. I feel like I keep making the wrong decisions, and I have a lot of regret (I'm trying to not to focus on it, just accept it and move on, but somehow I end up right at the beginning).

Any advice?
