mental hospital???

Today, well every day, has been rough. I talked to my therapist again today and I can tell she is feeling as helpless as I am. She recommended me to go to a mental hospital. I don't know much about them or what exactly happens there but if someone could reply with their experiences and whatnot that would be helpful. I seriously don't know what to do anymore and I don't even know if I should go to one. I'm trying to do research but all the information I have gained contradicts and isn't clear on what exactly happens and how it would help me. I'm also just scared lmao. I am scared what people not only inside but also outside would think of me. I also am scared I might end up even worse. I also don't want my mom to waste any more money on me than she already has. I can't take this any longer and I want to know if this is an option I can consider. If not, then I guess I'll just keep repeating this cycle until who knows what lol.
