I felt this way around this age and it is difficult. A couple of clichés I heard around this age grinded my gears but now in my 40s rang to be truth. "Nothing changes if nothing changes"
If you don't like how its going, where you work, who you date etc. Change it. No matter how difficult. The longer you prolong this the harder life will be. So get ahead of it and away from anything/anybody that doesn't make you happy. Life is so short being unhappy is aterrible way to spend the little time we have.
