An only child holds all the hopes and dreams of a horrid parent and their one chance for vicarious fulfillment second time around.  There is no sibling to help relieve the pressure.  

The nasty parent might insist you follow a career they hankered for but never achieved,  regardless of whether you have the talent or interest to pursue it.   They might nag you to be slim when they themselves are overweight,  marry someone rich when they are financially struggling and anything else from doing well in exams to keeping the family name going.  Being permanently under the watchful penetrating eye of  horrid parent is very stressful. 

We suggest that you try not to get involved in such arguments however annoying it is.   Instead  listen quietly, nod wisely or say something neutral like:  ‘Yes, I understand how you feel.  I’ll seriously think about it.’  It’s a  good way to mark time until you can leave home. Meanwhile keep reassuring yourself that like your parent you have just one life, and you have the right to choose  how to live it. Once you are independent you can follow your own path.  This doesn’t mean the criticisms and insults will cease, just that the parent’s  power over you will diminish.    

A single child can only share their thoughts about their difficult parent outside the immediate family. 

Keeping your feelings to yourself, either because of loyalty to the family or because it is difficult to trust anyone with such a sensitive subject, can make you feel lonely. CLICK ISOLATION. A positive aspect is that you learn to rely on yourself from an earlier age than most, learn to make your own decisions work through problems.  Spending a lot of time at home on your own will also help you learn to entertain yourself. 

An only child is likely to be responsible for their parents as they grow older, make major decisions about their welfare and deal with the practicalities.  This can be especially difficult as the nasty parent is ungrateful and rude.

We suggest you think about this demanding and tricky issue from time to time so you develop a general idea of how to cope and the responsibility involved.  Managing the situation in a  humane way could help you avoid a guilty conscience once they have died.  Doing the right thing also means you are less likely to pass on their bad behaviour to the next generation. But there are limits. Do what you feel is necessary, but don’t let your obligations intrude too much into your own life.  If looking out for them is a problem, it can help to think of them as a cantankerous old person you have chosen to visit rather than a parent.  The advantage of not having any siblings is that although you get to do all the work, you don’t have anyone arguing about your view. 

If as a child you associated mainly with adults be prepared for it to take practice to interact with your own age group.  It can also be difficult to relate to small children until you have your own.

We suggest you try to get involved with group activities, anything from sport, charity work, following a hobby.  It gives you something in common to talk about.  It is also a good learning space to watch how others interact and learn from that. 

Your home environment is one where your horrid parent’s view is the only one possible on world issues, personal matters and behaviour. 

 It's possible that outside your home you might need to learn how to negotiate disagreements without resorting to being unpleasant:  that there is more than one way to solve a problem and that other people’s viewpoints are as valid as your own. Listen to what others have to say, then present your view calmly.  Don’t copy your horrid parent and verbally destroy the person you are talking to because you disagree with them.   

Disagreeing with someone doesn’t mean your can’t have a relationship with them.  Don’t cut off friends automatically after an argument.  Every worthwhile relationship has its ups and down.  Write a list of the good things about any friendship before ending it.  Try to be a peacemaker outside of the home even if this isn’t possible with your parent. 

Learning how to argue with confidence while respecting another’s view is  more rewarding than an uncontrolled, irrational outburst and far less draining.
