First of all , I appreciate the fact that you decided to put it out here .
This feeling of being left behind is very common in this particular age group (20-30) being myself as a 25 years old , i can 100% relate to it . Knowing the fact that everyone has their own timescale is absolutely true but it only helps to a little extent.
In my opinion, the first thing you should start with is a Gratitude practice, i know its a very cliche advice but trust me it will help. Reminding yourself how lucky you’re to have everything around you and seeing your loved ones when you can , is a true blessing. How the things would be if you were born in an extreme circumstances , where you have to struggle to have good food and clothes ( how would the life be in that case).
Once you’re in a genuinely neutral or positive state of mind ,write on a paper what would you love to do ( 50 things ) . Getting a dance lesson , taking a solo trip , meeting someone new at a cafe.
And trust me you’ve got a lottt of time . Don’t worry about being married , buying a house. Once you’re genuinely happy with your life , your brain will subconsciously start revealing you ways to be more productive and ultimately earning more money and will also attract the right person for you . I’m sure you’ll be able to get anything you want .
Don’t force yourself for anything, calm down, flow like water. Start by accepting where you are right now.
Meditation, gratitude, positive books or podcasts.
All the best .
Shine on you crazy diamond, its just a beginning.
