Going out to GAL is hard, mostly because as you start you keep thinking about how it affects other people when the goal is only to make you a happy, whole person. Do *anything* that makes you healthy, social and occupies your time.
There are 2 self help books I would suggest (if you're looking) that can help you...No More Mr. Nice Guy (excellent book that helps men look at their lives and reach their potential) and Mindful Attraction Plan (more geared towards married men wanting more sex, but there's a fantastic checklist strategy to identifying parts of your life that are dragging you down so you can fix them).
They helped me a lot. I started this with zero friends, hobbies, activities, nothing...living with depressed people will do that, but after reading DB & DR, I now know how I should have reacted to the situation I was living in.
Resentment occurs when we aren't doing what we need to care for ourselves, though we expect others to do it for us.
