Need opinions or advice

hi😁 i’m ht. I’ve just joined & am needing support. I’ve never been diagnosed with OCD & would never sec diagnose but I struggle with a few things that are similar to the symptoms of OCD & am searching for some advice. So to start off, since I was 16 I have always done my own laundry. I don’t like others to put my clothes in the washer & wash them or put them in the dryer or hang/fold them. I don’t like others wearing my clothes, shoes or using anything of mine. especially without asking. I have a specific place for everything of mine. My clothes are organized by jeans then leggings then sweatpants then tshirts then tank tops then dresses then long sleeve shirts then sweatshirts then hoodies and they are ALL organized in their sections by most worn hung up first to least worn in the back (for example my tshirts are from most worn to least worn and then when I get to my tank tops I do the same thing) and all of my fold up clothes are organized pretty much the same. Everything has its place. My sister will often times go into my room whenever I am not home & take my clothes without asking & then doesn’t put them back in my room & I have spoke about this with her numerous times before & it doesn’t stop. I ended up buying a doorknob with a key & a few weeks after my dad kicked in my door & broke then knob and it has yet to be replaced. So I moved in with my boyfriend, his mom & his sister in July but I didn’t bring all of my clothes with me. Occasionally I’ll go back to my house to grab a specific article of clothing & I can’t find it. Whenever this happens, I get very irrationally angry & upset and overwhelmed with anxiety over my clothes being messed with & not in the right place. I cry & get very very angry and often times go off on whoever took it. After the feeling passes i usually feel horrible & end up apologizing while explaining why I reacted the way i did. So, with that…another issue is within the last 2 weeks, my boyfriends mom & sister have been going through my clothes & taking them as well. I notice that they’re gone bc I don’t have a whole bunch of clothes here. I first noticed it whenever my boyfriends mom came to tell me good morning and she was wearing my shirt. I have confronted them both everytime it has happened but no changes. Last night, his sister took 3 tshirts & 2 sweatshirts of mine. One of the shirts being a shirt my pawpaw gave me before he passed away. I went to go get them from out of her room but she locked her door before going to work. My boyfriend has tried so hard to defend me as well but they don’t listen. I have no idea if this is a sign of OCD or just me being upset that my things are not respected. I’ve never known anyone else who deals with these feelings when it comes to their things but if anyone on here does & has any advice on what I can do to help the situation & manage my emotions about materialistic things please let me know. I’m trying to be better & not let it upset me or affect my day to day life so much but I’m struggling to do so alone bc it feels no one understands.

also: due to financials at the moment, me & my bf can’t move out or else we would in a heartbeat.
