Welcome to HW, I believe you have come to a good place for your situation, since there are a lot of really helpful members and wonderful moderators here. We are all here to listen to you.
Maybe it is an idea to write down the things that are bothering you for a start. You don't have to post them on-line, since writing down your thoughts can be really personal and hard to share, and it will help even when you are not sharing them. However, we can try to help you better if we know what is bothering you.
I think it will be a good start if you tell us a bit more of your situation. You can write down whatever you want, and leave out the things you don't feel comfortable with sharing on-line (for now). Also, make it is long or as short as you think is necessary. Just throw out the things that are bothering you. If you don't feel like talking at all, that is also OK.
Hannah, please take care, and I hope to hear from you!
Yup , Erick is right. You should be writing things down. That is a good way of keeping things on track
