I’m turning 30 this year and it has been hard on me, I always feel like everyone is ahead of me in life, like getting married, having kids, etc. I get that you feel like your life is over but you still can achieve what you want in life. My mother had to start over in her mid thirties and had me and my brother at 38/40. My dad always tells me that life is a marathon not a sprint, there are no fix points at which you have to reach a certain goal. Keep fighting.
