Life is always more difficult than it appears via text and screen, I know this has been troubling you for some time.
I am also aware that you have an incredible passion for your content and talking about Notts, this is something you do well and put across your knowledge productively. You can develop burnouts from the demand, I did with Meet the Fans and much of the video content I used to do, but I would be lying if I didn't say I missed it. You've done right by putting yourself first at times, but as I have mentioned, it's only you who can decide about your channel's fate.
Taking a hiatus for a season wouldn't be a bad thing, the majority of fans would still be there when you return and a break could do you wonders.
You might feel the urge to continue vlogging with the promise of this upcoming season and there will always be disappointment one way or another. If Notts ends up having a good season, and you vlog - you will have documented it through the eyes of a fan. If you didn't, it may add to your regrets. Neither really matters because it's how you feel which comes first.
I'm speaking from experience when I say taking time away from something you care immensely about can be overwhelming, I have had low points and I regret battling through them without taking time to myself. Likewise, there have been times when I did take time and coming back felt much harder than going. I have mentioned how @GrannyPie had kept encouraging me to return to PON's social media. It felt difficult, as if I had to give answers, I really didn't. The issue is, what prompted my return wasn't right for me in the end. I needed to take further time off, including the site, just to re-find myself.
This isn't about me, however, I can draw comparisons and the point I am trying to make is you need to trust your own judgement.
You were pretty timid and reserved when I first met you, but I have seen you grow in confidence and flourish as a person. I know you have had many challenging moments, that's just what life throws at us. You will always be the same person, with or without your YouTube channel.
I meant what I said to you yesterday, I am always a message away, and you have never been a burden on me. I think you may want to take some time to think things over, maybe consider delaying your return to vlogging but only if it's unnecessary stress to you. Just remember the positives you get and outweigh things with how you feel. Your friends will still be there for you, just as I will be.
