ocd??

so there’s a lot but basically i’ve been told by my mum and also a few others in my family that they think i have ocd. i’m not sure if i do but i’ve been thinking and i came here to ask if these things are actually normal, there’s a lot of things i apparently do that i consider normal, some i probably won’t even think of bcos of that but a few is just, i “obsess” over things, things have to be a certain way, it’s almost like i start getting controlling because i like it done this way only, i get very annoyed bcos my mum doesn’t do something right, she says i’m always obsessed with things being a certain way, such as the things in my room or around the house. i think she’s over reacting and i’m just a tidy person. another thing she says i just obsess over things in general, i’ll have something in my mind and it NEEDS to go this way, i’ll keep asking and checking to make sure it’s right. i personally think those things are normal or just something that’s my personality, the only things i find weird which i’ve noticed within myself is that, i very often have vivid thoughts of my family and friends becoming injured or even dead, it’s very detailed and then if something bad eventually happens to one of them, i convince myself that it’s my fault, that i’m the reason that’s happened to them. i also sometimes get anxious when walking down the street bcos i have to avoid certain marks or details in the road, also think that’s fine it’s something everyone does but may as well bring it up. oh and also i do this thing with the light switches, i have to switch them on a certain way, the kitchen and the bathroom light are next to eachother, i need to use the same two fingers to turn them both on at the same time, every time i use one of the rooms, even if i’m not using the other, i also have to pull the door handle 6 times when i leave. i personally think those two are habits as well but i’m just worried now
