People are gonna get tired of constantly reaching out to you, and you not reciprocating. If you haven’t, call the person who always checks on you. Ask them how they are doing. Begin to appreciate the people who care about you. Acknowledge selfish behavior and strive to correct it.
I apologize if I ever was a toxic person in your life, I’m maturing more everyday, correcting my wrongs and slowly but surely becoming a better version of me.
