Am I a bad parent for throwing my daughter’s dirty guitar of 4 years away?

So I’m the same person who wrote about my teenage daughter hoarding trash in her OWN closet and left it there for three years. I apologize for posting on more than one sub, I need insight. As I mentioned before I have severe OCD. Especially when it comes to diseases and contamination. She told me she spit right inside her guitar a lot after I asked her what the white substance is inside the guitar opening while I was cleaning her room she laughed and tried to cover her phone on her face, after that I screamed and yelled at her and started crying. She had a look of horror on her face and said “mom please I’m sorry calm down I didn’t mean to”. I didn’t say a word and kept it in, wore gloves before touching the guitar and threw it directly in the trash she begged me to take it out and that it was her guitar for 4 years and I yelled no at her face and kept calling her disgusting for spitting in it and that if she’s gonna spit she should clean it instead of letting the dried up disgusting spit for years in there.

She went to her room and slammed the door, and after I cooled down I texted her and she won’t answer my texts. I don’t know what to do. I have severe stress during an ocd episode. I can’t help but wonder what if the saliva starts eating up the wood in the guitar and eventually eating up other objects in her room or my 6 year old daughter. I know it’s irrational, but all I know is spit has enzymes that break down stuff. I don’t know what to do and how to approach it all. I know some of you will come for me but my ocd is causing me enough stress as is.

The guitar is still outside in the trash and the garbage truck still didn’t take it, but can anyone convince me that the saliva won’t chew up the wood? I’m scared it will chew my hand up because it’s literally old saliva I know it’s irrational but that’s ocd for you. Yes I am getting treatment for my ocd. Now I feel like my whole house is contaminated I just don’t understand why my daughter is so dirty and careless.

I would like to add that she has a disgusting habits that likely made my ocd quadruple: hoarding trash, leaving dirty plates in her room till the next day (if I wasn’t there to clean she’ll leave it forever probably), hoarding dirty panties, wearing the same bra for god knows how long without washing it ever, picking her butt and smelling it and not washing her fingers after, and farting in her hands then smelling it, wearing the same smelly socks for a week (would go longer if I didn’t throw it in the laundry), spitting on the walls, and the guitar (I just found out). Even typing this out makes me feel so disgusted ugh. I don’t know how it came to this.
