well I went through a phase like that. You gotta find your calling or people you like working with to be comfortable.
The stress can be found in any job industry you get so it's something you need to deal with on a personal level. You don't want to bottle up stress or become stressed. Basically, deadline oriented industries, - legal, real estate, investments stock brokerage have that so you may do better in more relaxed industries: art, design, retail but again a deadline will exist. So, you need to handle stress better is what I think. If you cannot meet their unrealistic timeframes then ask for help or just do what you can, If you must work overtime make sure you are getting paid to do so. 1 or 2 hours overtime without pay though is not uncommon. It shows your dedication and organizational ability. a great attribute.
