Ok let me tell you what I think about life.
Baseline existence would be to be paralyzed and in pain, blind and deaf. There are people in this situation. I do agree that they have it bad - the only thing they are getting out of life is physical existence nothing else. They don't have much to be happy about at all. Some of them manage to, but I couldn't.
You and me though? We can hear, see, taste, touch, have much of our time without constant physical pain. Can read, hear music, dance, eat good food, enjoy a beautiful day, see a cute cat or dog. I just enjoy being physically embodied so much, and appreciate how good I have it.
Specifically though, as you are asking, the outward stuff got better in my early 40s. More money, better relationships, better job, gained some weight (I have mixed feelings about that but do feel physically healthier not underweight). Better emotional regulation, less hot-headed.
If you have some bad friends, find better people. If it's you who are the constant in the bad friendships though, you may need to consider that you may be the problem. Jobs are kinda different, I do think even sort of awful people can be successful in the right professional position.
