Thanks for providing more information.
I understand your concern.
And i think it's just your disinterest in such activities which make you anxious.
You feel impatient because of fear to face your father's reaction.
As it's human nature and it's normal that a person can't learn without his willing.
So you shouldn't worry and don't put negative impact on your life.
You are a free person and if you don't want to learn swimming and bicycling then you should ignore them.
You should prove yourself in other activities which you do with happiness.
If you still worry then it's good to get a counselling from a pyschologist which helps in handling such anxiety related issues.
Do meditation and deep breathing exercises.
I hope this helps.
