先来看一段美剧《老爸老妈浪漫史》S01E08节选：
Barney:(to
Ted) They’re edging you out.
Ted: No,
they’re not edging me out. He’s my best friend.
Barney:
Just keep your eyes open. That’s all I’m saying. Little things are gonna be
changing around that apartment.
Robin:(to
Barney) Come on, Barney. You’re just being paranoid.
大意：
Barney：（对Ted）他们在挤兑你。
Ted：他们没有挤兑我。他是我最好的朋友。
Barney：眼睛睁大点。我言尽于此。你们那个公寓恐怕要起风波了。
Robin：（对Barney）少来了。你想太多了。
我们谈论一个话题时，有时也会插进来一句“可能是我多虑了，但是……”，接着说出自己不同的看法。英语中也是一样的。
看《老友记》S02E02中的一段：
JULIE:
Ross is so crazy about you, and I really wanted you to like me, and, it's
probably me just being totally paranoid, but I kind of got the feeling that
maybe you don't.（Ross非常喜欢你，我也真心希望你能喜欢我，可能是我多虑了，但我隐约觉得你讨厌我。）
本篇我们来讲一下“多虑、想太多”，英语怎么表达。
1. paranoid: someone who is paranoid is worried all
the time that people do not like them, that bad things are going to happen to
them etc., when this is not true原意是“过分猜疑的；妄想的”，形容一个人“多虑”，总担心别人不喜欢他，有不好的事要发生，等等。
例：
I was so
paranoid at one point that I was refusing to answer the door.（我一时太多疑，没去开门。）
The
mysterious phone calls were beginning to make him feel paranoid.（神秘电话开始让他疑神疑鬼。）
By 1982,
he was so paranoid about his health that he wore plastic gloves at all times.（他总过分担心健康问题，所以到1982年他都一直带着塑料手套。）
2. have a lot on your mind: to have a lot of problems
to worry about, especially when this means that you do not concentrate on other
things表示“要担心很多事，无暇他顾”
例：
Since
the divorce, Linda's had a lot on her mind.（离婚后，琳达心事重重，无暇他顾。）
I'm
sorry I wasn't paying attention; I have a lot on my mind at the moment.（不好意思，我刚才走神了，想心事了。）
3.
stressed out: so worried and tired from problems you have to deal with
continuously that you cannot relax 表示“事情太多，感到焦虑、心力交瘁、身心俱疲”
例：
I always
eat when I'm feeling stressed out.（我感到焦虑时，就不停地吃。）
By the
end of the tour, the band was totally stressed out.（巡回演出结束，整个乐队都心力交瘁了。）
One of
my adult students was a stressed-out mother.（我的成年学生中，有一个是天天担心子女的母亲。）
I'm
trying to have a few early nights because I'm feeling stressed out at the
moment.（这几天我得早睡，因为事情太多，有点身心俱疲了。）
4.
preoccupied: worrying so much about a particular problem that you cannot think
about anything else表示“过分担心某事，而显得心不在焉”
例：
What's
wrong with Cindy? She seems a little preoccupied.（辛迪怎么了？她看上去有点心不在焉。）
He's completely preoccupied with all the wedding preparations at the moment.（他这会正全身心地筹备婚礼，无暇他顾。）
