I'm not sure what I should do, I had a dream and my therapist was in my dream, by the way the dream was NOT sexual. I am wondering if I should tell him about my dream or not????

I am a sixteen year old female who is sexually attracted to her own mother. I'm incredibly ashamed of it and I have no idea why I feel this way. I don't find her attractive. And I've actually had an absolutely horrible relationship with her ever since i was 13 and I cannot stand the woman.
Honestly, the relationship is so horrible. I have trouble hearing her voice without getting incredibly pissed off. But recently I've been getting so angry, that I actually become turned on. Now, the littlest things she does that used to make me so angry, now turn me on. For example, the way she handles everything so delicately, how soft her voice is...ect. ect.

I've been feeling this way for about 6 months and its been progressively getting worse. Now I find it invading my thoughts, and being on my mind frequently.
I have struggled with OCD in the past... Obsessive thoughts about things such as incest and bestiality .. but I've never had problems with obsessive thinking AND erotic feelings.

Please. help. I've attempted suicide because of this, and I haven't been able to bring myself to tell my therapist or psychiatrist.
I have looked on some forums saying that feeling sexually attracted to a family member is more common than people realize... which makes me feel a little bit better.

But I would like to know why on earth do I feel this way? And how can I make it go away?

Alright let me start this off with some context, I am a 18 year old senior who's life revolves around animals. At my house I have a cat and 7 reptiles (all mine), but at my grandparents who i vist every weeked, has not just a cat, but a spawn of pure evil. Now this cat we bought from a home as a kitten and raise it up to the evil it is today, it has never been abused and has a life full of enrichment amd everything it needs. But even so this cat does not let anyone pet it, it never purs, it breaks stuff, attacks at random, and has a ever growing desire to murder. My cat at home is the complete oppisite, so needless to say I was taken back by the attitude, and tried many things to correct this behavior. But recently I have had this ever burning passion to strangle the cat, step on its neck, or simply kill it in anyway possible. This started when the cat decided to ######6 fling one of my gecko enlosers across the room, break in, and eat its tail. It must have thought the taste was good too, because now she wont ######6 leave any of my enclosures alone and i have to hide them in the basement. Ever since she touched my precious child, I've felt this way, and I have given up on trying to fix whatever mental problem this cat has, because whenever I see it, I get a visual image in my mind of abusing the thing. This freaks me out, I would never hurt my other animals or even my cat, but this ######6 evil has me going crazy, and these thoughts i have need to stop.

Thank you for your time
I am currently a male upperclassmen in high school. My grades are... For lack of a more accurate word bad, I have about a 2.0 cumulative. I used to want to be a 2d animator you know like cartoons. When I think about it that goal it is as far as can be from my reach. About a year and 4 months ago I saw this girl who is now the only thing I think about, I talk to her In very small conversations daily, she is the only reason I even want to go to school when I'm in class I zone out and just think about her I would do anything, everything, and more to make her smile. I go home from school too depressed that I'm not more to her than just someone to talk to for ten-twenty minutes and forget my homework and just think about her, cry for a few hours. Then my mother gets home and it's time for me to fake a smile and make sure she never worries about me. I usually talk to friends on skype which surprisingly takes my mind off of her a little bit, then nighttime comes and I'm back in bed crying,shaking, tired but too scared of how bad my depression may get if I don't keep working for her I've even caught myself whispering her name and talking about how much I love her when I'm in this state. So I'm trapped in this cycle, I ignore school and think of her then I remember she's the one and only thing I would ever work for and my grades just keep dropping. The one funny thing, nobody knows I have this problem, I seem so mentally stable, and I have plenty of friends, I'm only lonely because i avoid talking to people sometimes so I can just lay in bed and think about her. I had brought this problem to a different site and I was banned within a day (I must've swore or something) and I felt like nobody could help me, i have 3 ways I think of my life going, either I end up with this girl that I would be as loyal as a dog too, I somehow manage to pursue my dream of being an animator, or I don't end up with her and my depression takes over, and It scares me so much. Please just give me feedback, I need this help I feel empty.

Is it abonormal that whenever I gain interest in a certain show or game that all of a sudden I drop literally all my other interests and focus mainly on one character in that series/game. It gets so bad that I'll actually imagine myself being in a relationship with them and also adopt most of not all of their traits and pretend I've always acted like that when in reality I was different before hand. But then again that could've been another character. I've been doing this for near 10 years so I don't even know who I am anymore. It's frustrating and I'm honestly concerned as it's nearly ended friendships in the past. In order to stop it, I've tryed asking myself am I doing this as me or as the character. This has proved unsuccessful as it just makes me paranoid that I'm being a character when I do something the same way I'd imagine the character doing something. It could be the most mundane task ever and I'll still be paranoid that I'm not me but someone else.
