Who is in lalaland? The "friends?"
It's difficult becoming an Adult. Everyone struggles. Jelousy steps in. Ego.
You can count your friends on one hand, in a life time and it often takes a life time to work out who they are.
Continue your own dreams, desires and success what ever that is. Stand tall.
Your aquaintences, yes that is what they are will walk away when they are ready. Only let people into your life in the future that actually click and show respect and visa versa.
