Today was my uncle\u2019s birthday and we had a good time, going to lunch, then going to the universal studios city walk and getting candy, on our way to dinner my uncle sees his old truck that he\u2019s letting my grandfather use and so we stop to say hi and all that. Although one thing I didn\u2019t know was that my dad, the one that has never been there for me ever was now wanting to talk with me about life and everything and idk how to feel, with my mom trying to be back in the picture but not wanting to respond to me or anything and my sister being born a few months ago, and now my dad trying to be back in the picture without it feeling like he truly cares and I just don\u2019t know what to do. Should I let him into my life or should I keep him out? I just have severe mental issues and all that and I don\u2019t know whether to be angry or cry or be happy or what. I just need help to figure out how to go through this. I want to show mercy and let him in but the things that have happened make me not want to. What should I do?
