Looking for suggestions to improve productivity while working remotely

I am a freelancer working remotely for my clients and one of major struggle I have is staying focussed and avoiding procrastination. It takes me way too long to get started and once I am able to get started and feel focussed then that feels like such a good zone to be in. But this way of operating is definitely not very healthy and lately I've been feeling mentally really exhausted.

While looking for some solutions, I did get recommendations for using apps such as forest, or virtual coworking tools such as focusmate, etc. But I want to understand if it's worth using these tools or if the folks here have some other suggestions? Thanks in advance! :)
