In my case it took a major life event of losing my father and my best friend to shove me in the right direction, but these changes take time. One of my good friends has been working on becoming a better, more well rounded person for a long time because of the "little pains" and is finally starting to see big changes after about 2 or 3 years of progress.

Dont give up! There is always time to be a better person that you yourself can be proud of. You never stop improving till the day you die, so just stick with it and you will be making moves that you will be so so proud of.

The only advice that I can personally give you is that you need to start off with only making moves that you are confident you can stick to. Dont upend your whole life at once! If you want to keep a garden, for example, try one plant first! Its a lot easier to keep a cactus alive than a flowerbed

Best of luck to you
