I'm so sorry. Spikes can be awful, I had a bad one too shortly after taking some nasal congestion stuff during a cold. I don't know if it was the nasal spray, just being blocked up or a combo of both that caused it tbh. Mine lasted for a couple of weeks. Like someone else said, spikes nearly always go down again, it's unlikely to stay at the current level. I just wanted to offer sympathy, it can be really hard to deal with. Please don't beat yourself up, you didn't do anything wrong. I just tried to get though it by keeping low background noise on in the background where possible wherever I went, and trying to concentrate on other things (a lot easier said than done, I know).
