Feeling like I’m going crazy

So I’ve been struggling with the fear of losing my mind lately. My brain has been trying to convince me that I’m gonna lose it at any second. I was having some pretty bizarre intrusive thoughts recently and I started to question if I was becoming delusional or not. When I would get the intrusive thought I would panic, thinking I was really losing touch with reality. Now my Brain is checking to see if I’m hearing voices, so I will picture a weird sound in my head and then freak out thinking I’m hearing something. It kept happening over and over until it was all I was thinking about and the I ended up having a panic attack thinking I was going crazy. Has this happened to anyone else? I really need advice. Thank you in advance!
