overthinking/anxiety/weakmind/poor judgement

My parents are both the youngest in their families. My mom is from Punjab and my dad from uttaranchal. They are in many ways not that knowledgable and are normal people with simple needs. My dad I think is not very smart and the way I was raised he ingrained in me to be nice to others all the time. He never did sports nor has he ever been keen in my sports interests which still get me mad till this day. He also lost all his hair by the age of 30 he says its because of stress. My mom is brave than my dad I think in many ways. My dad never taught me to speak up for my self. I was bullied on many instances since I was a kid. Its almost like if you are raised up good you dont feel like doing bad or certain actions just disturb you so you never dare them so hardly ever stand up for myself. I have always been socially shy and have low confidence that Its not for me to be like that and kind of dont believe in my self. I almost never argue even when Im right.I think myself to defeat even before I start. Its weird because even though I know thats wrong with me I cant stop the process of worrying. Everybody says im too nice. and when that nice- ness gets the best of me I many times become frustrated and have after thoughts and regrets of how differently I should have handled the situation. I get tartled easy by sounds etc. But when I get comfortable in a situation man I have never seen this much confidence in my friends or poeple around me. I started to fight (boxing)in the amatures 2 and a half years ago and used to spar ranked kids here in Texas. Yet my girlfriend used to tell me that im meek and need to speak up more. I started developing fat tumors all over my body in the past 6-7 years or so. they are like small round balls of fat but the doc said they arent harmful. I have had a deviated nasal septum and as I cant breathe thru my right nostril I always constantly feel irritated and hard to focus. I have a underdeveloped upper jaw and so I have Obstructive sleep apnea. I get weird dreams almost constantly at night and speacilly while I am about to wake up. These days I dont get hungry maybe because I am sad that I broke up with my girlfriend. I dont feel like running or doing anything physical for that fact. I also wobble when i walk sometimes maybe due to my flat feet and am imbalance and I thinking about not wobbling. I am very consious in public. specially since I moved to the states in 2006 when I was 17. I procrastinate alot. But when I get into something I always wear my self out because I get obssessed with it or just over do it. I always try to stay away from confrontation. But when I do confront I just punch people in the face cuz I dont believe I can verbally win.
