Or should I stick with my DPS vacation? I was actually crushing it last night. Even got the “winning trend” modifier. Not sure if I want to risk spoiling the good morale with another potential Support matchmaking disaster
When you’re hesitant to play your actual main role 
You call playing DPS a vacation? I find that role way too difficult and stressful to play for any extended period of time tbh 
Tank & support are way more chill for me.
To actually answer your question though, I’d say that if the memory of your bad support experience is still fresh and weighing too heavily on your mind, it’s probably a better idea to not go back just yet. Take all the time you need to fully regain your strength so that when you do eventually return, you’ll have the drive to push your limits even further than before.
To me, DPS is a vacation because I only have one consistent main goal to focus on: destroy the enemy. Or distract them in a way that leads to them getting destroyed. There may be other aspects to any given hero, especially Mei out of my DPS mains, but the underlying goal remains the same. I don’t have to worry about whether I’m neglecting some other duty (healing), or if “neglecting” said duty is actually the right thing to do in the moment or not, while I’m trying to delete someone. I just go and try to get it done. There’s a lot of independence, which is nice
On Support, I’m currently going through a “panic” rut. The kind where I ping enemies so much that I can’t actually focus on dueling them, and I’m too distracted with the idea that I should be healing someone to really go on the attack when it’s needed. And then I get tilted to the point of madness. This happens sometimes and I don’t know why. It should be something that I just need to overcome once and forget about
Welp, actually it’s that combined with me getting matches that probably would be losses regardless
Play both, just go back and forth between the 2 and see which you are feeling more today. As long as your having fun and enjoy playing thats all that matters.
Its what i do when I dont know if its a support kind of day or dps.
Hmmm… I’m not sure how helpful this would be, but have you tried playing FFA deathmatch? Waaay back in 2017 when they added it, I was playing a lot of Zen at the time, and I found FFA pretty useful for honing my dueling skills, so that in my actual matches I was a lot more confident with orbing Genjis in the face whenever they’d get all up in my business. I’d suggest giving it a shot, if for nothing else, then to at least just practice your mechanics and such.
Queue for them both and play whichever role you’re throw into
Sounds like you should stick with DPS for a while longer. It’ll build up your blood lust, so when you go back to Support, you will be ready to take those kills without hesitation.
I used to play FFA a lot before I got sick of various things about it. I basically onetricked Brig and later LW there. It’s different because there are no dying teammates to distract me. What I need to do is learn how to suppress the distraction that they cause. Even when I’m just being attacked by a flanker, I think the distraction plays a subconscious role in the panic. That and a preoccupation with the fact that my co-Support could be helping me, but usually isn’t. That irks me more than anything the other teammates are (or aren’t) doing. I bail my co-supports out of things all the time. They rarely do the same for me
I did that yesterday. DPS matches were fine, but the Support matches drove me insane (just the latest in a series of bad ones over time). That’s when I declared that I was escaping to the DPS role exclusively for some period of time
