I cannot get myself motivated to fix my life

I am a 27 year old (F) and have PMOS. I have not addressed my PMOS really at all and I know its affecting my life.

I work a shitty job taking care of plants for businesses around my city. Sounds sweet but has been a nightmare dealing with garbage co workers and people daily. I'm an introvert and did not expect this job to deal with so many people. I've been looking for something different but can't find anything.

I have my own endeavors I want to accomplish. I want to be healthier. But I just can't seem to motivate myself to do them whatsoever.

Here's how I describe most of my life. I try to plan a to do list. I will follow it for 2 days. Then I'll forget about it and be at square one, staring at my computer unsure of what to do. Even things I like doing can be difficult. And if I have to do things I don't like, it's hell. It's literally like a wall is up mentally for me. It's like walking through mud. If I hate doing something I'll shittly do it with no effort just to say it's done. This can also sometimes apply to things I like.

I want to be better. Healthier. But I'm just stuck in a limbo. I CANNOT afford therapy or medication right now and have no clue how to go about even getting low cost help.

I just feel lost and broken.
