You seem to been a victim of your opponents tactic to fall prey to your emotions. Your questions and actions also are in line with your opponents advocate strategy.
To take objections and make the litigant suffer through the process of law is an art and thats what lawyers get paid for (also at times in not making their client suffer the process of law).
There is a proverb
'A man who is his own lawyer has a fool for a client'
This proverb is based on the opinion, probably first expressed by a lawyer, that self-representation in court is likely to end badly. Ref: https://www.phrases.org.uk/meanings/a-man-who-is-his-own-lawyer-has-a-fool-for-a-client.html
This adage has two distinct aspects. The first addresses a principle in American law that allows an individual to represent himself or herself in most judicial proceedings, such as criminal or civil trials. This is called acting pro se, whcih is Latin meaning for oneself.
While this is a right afforded a party (civil case) or defendant (criminal case), legal rules are complex and arcane, and the task can be challenging for one trained in the law, let alone one who has no formal legal education or experience. In this case, the phrase means
This is tough stuff. You would be foolish if you try to represent yourself.
Because of this, many judges, especially in criminal cases, will require that the person representing himself or herself have a shadow counsel available to assist. The shadow counsel does not lead in the arguments or examinations, but is on call as will try to guide the pro se defendant or party informally.
The second aspect of this saying covers the circumstance where someone who is a lawyer tries to represent himself or herself. Most lawyers and judges believe that the same rules apply as if the defendant or party were a lay person. In fact, some would argue that a lawyer representing his or her own interest is even more foolish than a lay person.
A lawyer may have the arrogant view that she or he knows the law and is an excellent advocate. Right or wrong in that analysis, as an involved party, the lawyer is unlikely to be as objective about the case as an independent counsel. That involvement, almost always emotionally charged, may distort the handling of the case, usually to the lawyer's detriment. Judges will often insist on shadow counsel even when the pro se defendant is a lawyer.
Many (especially lawyers) would say
A man (or woman) who is his (her) own lawyer has a fool for his client.
A lawyer who represents himself (herself) has a client who is an even bigger fool.
Well, that said I would let you find it for yourself how it goes and credit or discount the proverb with you own experience.
