I got into altcoin trading just recently, a week or so ago.
Honestly I never dealt with exchanges before and this is all new to me but it's both fun and very stressful. I'm not a big time player, in fact I started out with nothing and just mined some Hush, sold that and bought ARK/Waves/Shift/Espers. I own maybe $500 worth of coins right now lol, but I plan to increase this.
However stress is getting to me. I keep checking the prices, trying to buy low and sell high and I do that at work now as well and even dream about it. I dreamed Espers was getting pumped and my exchange closed Espers trading and I woke up all pissed off and sweaty and cursing the non existent exchange.
I'm not very interested in the tehnology I just want to trade as I find that a lot of fun. But I need to deal with the stress somehow

Dealing with stress is simple if we think but difficult to do. But I suggest that if your stressed and angry, better stop what you're doing and do things that make you happy or make you calm. It might ruined the things you're actually doing if you're stress just chill for a moment and make fun.
