I feel lonely everyday. There are several reasons for it. I left the country where I was bot and raised after 32 years of life and came to my current country of residence as an immigrant. I grew up speaking English and although there is nothing that would distinguish me from a person born in my 2nd country, I find that the lack of shared life experiences with the people around me has isolated me to a great extent. People often prefer to hang out with friends they've known for a long time and gone to high school with. I don't have a single good friend in the 3 years I've been here.
I also struggle with self esteem issues. I always have. Thus goes back to my early childhood and I a learning to keep those feelings under control with help from a counsellor.
It's nice to have people to talk to and share feelings with. Don't give up on being nice and trying to connect with people. You will eventually find people you like. If you feel you're struggling too much, seek help from a professional. Talk.
