No.
Don't worry too much, it is all easy enough to solve and the car will be back to top form in the end, assuming the work is done successfully.
This is something that happens with age to all engines, simply due to the typical degradation effects of time on rubber material. It is expected and completely normal to have to renew these seals sooner or later. Most of us on here have experienced it, and once you get it handled, everything will be as good as new.
But it does sound like you are in need of a complete reseal of the injection pump at this point, rather than trying to patch leaks here and there.
You're right to be cautious about the process of getting the injection pump timing right when removing and reinstalling the pump, which will be required to fully reseal it. (Most of the seals can be done with it mounted on the engine, but not all.) However, the timing procedure is not rocket science and is a standard part of the timing belt replacement process as well. It's certainly good to be careful and smart about it, but not so much that you need to fear it or try to avoid it in a case like this where it is simply necessary. The trick is just getting the right person to do it, one who has the ability, equipment, information, and intention to do it right.
Who has done your timing belt replacements for you in the past? If you have a capable mechanic who handles those (and has the correct tools and has proven their ability to do the job successfully), then your best option will be to bring the car to them for this work. They can remove the IP, and then you can take it to a certified Bosch rebuilder, or send to Tom Bryant here in the US, or Diesel Bob in the UK or whomever you choose to reseal the pump and bench-calibrate it. Then your qualified mechanic can reinstall the renewed pump and get it timed correctly for you.
Finally, as ngoma mentioned in your other thread, you should be very careful to ensure that the heater hoses that run underneath the injection pump do not get damaged as a result of coming into contact with diesel fuel from the leaking pump, OR from the process of making repairs on it. Even small quantities of fuel will ruin the hoses if there is prolonged contact. That WILL lead to the hoses rupturing, which will quickly overheat and damage the engine.
If you are in any doubt about this, we can help you with replacing those hoses after you get the fuel leaks fixed. There are ways you can improve the routing of the hoses so that they avoid the possibility of fuel contact in the future.
