It sounds like you are on the right track. I have just started feeling better after more than 10 years of depression and so much of what you said makes so much sense to me.

That I might not be perfect, I might be far from perfect but I can rely on myself to live a meaningful life.

You can trust yourself and have rely on yourself. You can move on from the people and things that hold you back and you can meet people who are good for you and value you as much as you value you them.
