What is your definition of psychology ?

I self harmed for two years. I began starting a new coping skill that has been really effective; eating. Although, I'm worried because I had a slight eating disorder before, eating might draw me back in it agaian.

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.

I carry around a little pocket knife , when its just me and my daughter home. I won't take a nap when my daughter is sleeping aswell because I'm scared someone might take her while im sleeping or threaten to hurt her to make me do things. My mind continuously comes up with bad situations (example-if someone is knocking at the door I get paranoid they might force there way inside and hurt me or my family so ignore it but then I think if I ignore it they might think no ones home and break in ). I feel safe when my partner and everyone is home, but when its bedtime I lay awake and feel like someone's watching me from the windows or is going to break In and kill all of us. When I dose off I wake up scared when I feel my partner is gone and I jump to conclusions he has been dragged away and stabbed but in reality he just goes to the toilet a lot during the night . I usually end up grabbing a knife and putting it safely near me till I finally fall asleep which normally is around 3 in the morning. I feel it's my job to protect my family and if I let my guard down, someone will take their life's away and mine. I try to talk to my partner about it but he just says "stop thinking silly", I'm trying to stop but its not easy. Am I just to paranoid or crazy...

I've been having pure o OCD for a long time. I was never properly diagnosed, but I've been having obsessions ever since 3rd grade. Lately I started to obsessing over my sexuality, even though I've already had a crush on a boy in my school. I got over my HOCD, and after a day of pure relief, when I was scrolling through YouTube, I found a video about a trans. Immediately a thought popped in my head, "What if I am transgender?" I started to obsess over that. I am tomboy-I had a lot of the character traits and humor of boys, my voice sounded slightly deeper than other girls, I was different than other girly girls, I hate pink, my childhood toys were cars, and I even looked kind of like a boy. However, I always loved being a girl. I felt quite comfortable in my body-and I've never disliked being called 'her' and 'she'. I've had a lot of fantasies and daydreams, all of which I was a girl. I imagined myself growing old as a girl. I've always believed/identified I was female, and that was what I told myself when I first started to obsess. As time worn on, I became less sure. Every time I look in the mirror, I felt ugly and boyish. I don't want to be transgender. I keep on having unwanted thoughts m=of y=myself as a boy-I don't want to think about what it ould be like to be male because I'm scared I might like it. I dont know if I'm actually trans in denial or just TOCD. Please help!
