How do you change your lifestyle for the better and become a better healthier person?

I’m 21 I have no motivation, I’m always tired, with or without kids.

I eat fast food every day.

I don’t workout, I have no motivation or energy to clean.

I’m also bipolar, which plays a big part, actually why I constantly spend money.

I want to be better for my kids and husband, but it’s just so hard, since I’m bipolar I have no friends, everyone is afraid of my temper and doesn’t want to be around me because of it.

So it ultimately will be me on my own doing this.

How do you do it?
