I can't say I'm not important to people cause I know there are people who find me important for instance the seniors I work with. But other then my professional work life I don't have very many friends. I am always at home alone for weekends and on my days off of work I am at home doing nothing. I find it so hard to be social with people of my age. I only have 3 friends my age and I only really hangout with one. I try to contact people my age but they usually send on message back then never reply or they just never reply at all. Why is it so hard to find people my age to get along with.
You know, I was once feeling frustratingly ignored by my peers until I realized that friends weren't limited to any age group. Friends can come in different shapes and ages as long as they are true to the meaning of friends. For instance, I only have 3 friends in my age group, the rest are either younger or much older (10 - 30+ years older). Regardless of their age, they have been so supportive and understanding when I was having a tough time.
So don't exclude the people not within your age group. When you start looking and reaching out, you'll find that people that you consider friends are not really friends, and the people that you'd never have thought of as friends are the truest friends.
Change your perspective and you'll see great things. Good luck!
