I'm really lazy feel like I have no energy tasks feel like climbing a mountain how do I get over this?

I struggle with tasks doing things on time I know it should be done but I feel like I have to drag myself up a mountain to even start it if I manage to start it if it feels like it'll take ages I lose focus I do however find it alot easier to do things when it's smaller or I'm listening to music but I still struggle with some tasks even looking after myself sometimes I'll do things as fast as possible I want to be able to get into routine and stick to it any tips or advice please I would really appreciate it thankyou
