Sensory issues

It’s getting really bad. I’m in such a bad place in my life right now. Having daily meltdowns and just feeling so out of control of my own emotions. I live with my parents and we just moved house but the floors are so thin here I can hear every bit of noise and I feel like I’m going insane. It’s so horrible. I’m in my bedroom just trying to get some quiet and time alone and I can hear full conversations from the lounge below me. It’s hell. Like I can’t cope like that, I just can’t. I have my earphones in all day but I’m still anxious because it’s like I’m trying to compete with the noise - I have to have my music so loud that I’ve been experiencing headaches. And then when I want to pause my music I know I’m going to hear all that noise - it’s no way to live. I’m not living right now. I feel like I have gone backwards in my life. It’s so upsetting to me. I have no one to talk to - my boyfriend is neurotypical and he just doesn’t understand my emotions. He shuts down when I’m emotional and says he doesn’t know what to say. So when I call him when I’m struggling it makes me feel more frustrated. I honestly don’t know how I can carry on like this. My mum said she would help me rent a flat - but now I’m paranoid that there will be noise there too!! What do I do?! I can’t live here but also I’m not sure about living anywhere else. I’ve got a lot coming up in my life too, like university and finding a new job - how am I supposed to do those things while my living situation is like this? It’s just a nightmare. I don’t know why I’m posting this. I know there is no solution. I guess I just feel so hopeless and alone and looking for a glimmer of hope.
