First, forgive me for the long post, but I'm not sure how to articulate my anger and frustration in a few short sentences. I feel like a background is necessary to understand how I feel, maybe not but bear with me. I was emotionally and physically abused as a child, I lost both my biological parents, and my adoptive parents aren't so good either. I feel like my adoptive father never taught me how to be a "man". That makes me angry. My mom is the "alpha" in the family. I love them but I feel like they could of done better. Perhaps I'm just blaming everyone else, but how can I be a healthy man when the primary caregivers in my life have done nothing for me. Correct me if I'm wrong because I'm not sure. I had a shitty high school experience. (Couldn't talk to girls, few friends, played video games all day, massive fear and anxiety). I'm sure this sounds familiar for some of you. I'm depressed, i think about suicide, and I don't know what I want in life. Well that's partly true, I want to be happy and feel loved. (Maslow's hierarchy) Stay with me, it's hard to put the massive amount of thoughts in my mind into words. I know you hear this shit all the time but I have oneitis for my best friend (a girl). 3 fucking years of pain, jealousy, and hearing her talk about how she wants to fuck 4 of her guy friends while also dating someone. 3 fucking years of her telling me "you're my brother, we'll always be friends, I love you, I need you in my life". Yes the best option is to cut her out if my life, easier said than done. I tried for a month not talking to her but was bombarded with emails telling me how much she loves me. It's hard for me to cut out the only person in my life who gives me attention even if its not the attention I really want. She knows how I feel, I've told her many times. She's told me she might be a lesbian(she actually was in a relationship with a girl in high school). She says the guys she sleeps with don't mean anything to her and she only wants then for the physical. Those words always bring me hope that one day she"ll love me even though it is highly unlikely. Yes I'm a fucking doormat and she is the alpha and I am the beta. I can't blame her for not liking me. I have no self respect so how can she respect me. And yes, she's told me I'm a great guy and any girl would be lucky to be with me. God I hate those words!!!! You're probably tired of listening to this same story a thousand times but I'm truly lost. I found this subreddit and I'm not sure what to think yet. I believe self improvement is the first step. I just need some fucking guidance. What do I do with this girl? Cut her out? Am I crazy? I need someone to fucking tell me the honest truth. I need someone to guide me or at least get me started on the right path to become a healthy man who can be proud of himself. Is that too much to ask? If you've read this thanks, and forgive me for the jumbled thoughts.
