We all go through our ups and downs , you were in a phase in your life that was clearly emotionally difficult for you as it is for most , and often financially difficult to allow growth (most socialising,hobbies etc requires energy and money) , so don't be so hard on yourself. It is also okay to drift away from people , everyone experiences life differently , maybe in the future your paths will cross again ,maybe this will create space for people which are more aligned to who you are now. Just take it easy and congratulations on your employment.

Take this time to make new friends. People outgrow each other. Its a part of life. Let go of the past. Make some new memories.

Don't be too hard on yourself. It's still early in the game for you.
