Hi @AlltheJays23
Firstly I'm so sorry you're going through this level of distress. I suffer from extreme anxiety and PTSD and sometimes it tips into obsessing and OCD and paranoia. I can't say as I have experienced 'auditory hallucinations' or hearing noises that aren't real -but- try not to panic.
My best advice is when feeling this agitated is to identify it and take action - proactive action - to get yourself in a calmer and less angsty state. Sounds blindingly obvious to say that and I'm not trying to be patronising, I just know what works and what feeds it. You have to stop 'feeding it' - we have to 'fight it'.
Are you prescribed any medication such as anti anxiety medication or sleeping tablets? If so, use them.
Can you force yourself to do things that are calming and relaxing such as take a hotwater bottle to bed, wear cozy clothes, snuggle in your blankets, and watch something silly and daft online like a favourite old comedy show or a children's TV show or listen to an audiobook? I find having a hot bath a bit too much of an ordeal and it's such a cliche but a lovely hot bath soak can work miracles. Lavender oil or infusion or spray.
Distract distract distract from your own internal monologue and thinking - that's where the damage lies. Also, eat some nice yummy food. Eat well! I personally don't eat junk food or what I call 'sugary shite' for comfort as it makes more problems but I'm a great fan of a couple of chunky stodgy sandwiches or a bowl of pasta or a portion of chips or some mashed potato with gravy or a big bowl of soup. It's calming.
Do you have any vitamin or mineral supplements ? Magnesium and zinc can be calming.
Cut out excessive incoming stress - so, put your phone on silent, don't make any agreements or arrangements to do things you can't cope with for the moment. Don't watch the news, horror films, or engage in critical gossip about others. This is about you getting into radical 'self care' mode and hunkering down to soothe yourself.
Can you get yourself out for a walk tomorrow? Put on warm rainproof clothes and force yourself to the park or nearest green space. I talk to trees when it all gets to much. It works miracles.
Please believe in yourself and that this is just a blip, it's because you're abnormally stressed or ground down somehow - even if it's unconscious there's 'something' - and you're going to get real calm, real relaxed, play it hour by hour and get well fed, drink calming hot drinks. Do not drink any alcohol or smoke any weed, do not eat sugary shite junk sweets. Be very very kind and gentle on yourself and rest up. Don't expect anything from yourself and play it hour by hour. Don't let yourself think beyond the next hour. Block out the obsessive thoughts - play music or audiobooks etc. YOU CAN DO THIS!!
