Hi @Rachel5, I'm sorry you're feeling this way. I know the feeling too well and it's not an easy one to deal with. The one thing I would say for advice is don't let it fester. It's so easy to fall into a place where you start to feel lonely and sad and like there's no point to life. I spent so much time sitting in that space too scared to ask for help or do anything about it and my biggest regret is how much time I spent being miserable when I didn't have to be. It's not easy to ask for help and I know therapy isn't always accessible to everyone but as a person who struggles to open up to people I'm close to, therapy has been really good even if it all it gives you is a safe space to talk to someone. Otherwise, just talk to someone about it, lean on someone and let yourself be cared for. Even if that just is on here, or lifeline etc. Just remember to be kind to yourself especially on days when you feel low and know you're not alone.
