Sometimes it is necessary to move on from certain situations, could be work, friends or even family if they are toxic to your well being.
New friends take time to make, to trust. Patience is important.
I'm shy so making friends is not easy. I also assume people won't like me, or will find me boring.
Now I practice positive affirmations when meeting new people, like, repeating;
I like them and they like me, over and over again, to reduce my anxiety.
And, in time it works!
