Developing your own film and producing prints from them is terrific fun and hugely rewarding.
Its really hard to totally ruin a film but its quite easy to mess it up enough to affect the quality of your work.
However, with a few simple precautions you will be able to produce workable negatives
The biggest problem you are going to have is dust.
You need to figure out how to keep your Developing Tanks, Changing Bag/Tent and associated equipment clean and dust free when not in use.
Probably need to investigate food containers with waterproof seals to keep the Dev Tanks and Changing Tent inside.
They need to be put away clean and absolutely dry, then when you want to use them, give the outside of the container and rinse under the tap, or a good wet dusting before opening with just washed and dried hands
A Changing Tent is probably better than a Changing Bag as you can easily wet dust (using a wet cloth microfiber duster) the inside of a Tent but not a cloth Bag
I use one of these Harrison Changing Tents -

Dust on stuff like Measuring Cylinders is fairly easy you need to give them all a good wash just before you use them as they are all designed to be used wet
As others have previously mentioned, a place to leave wet film to hang while it dries is essential, an empty wardrobe is almost perfect. It just needs a wet dusting inside and out before being used.
The whole room in which you are developing the film in and then drying it in will need to be wet dusted before you start wet dusting gathers up the dust that has settled and gives airborne dust something to stick to.
Bathroom or Toilet is often a good place somewhere with a sealed or linoleum covered floor not carpets
All the water you use will have to be filtered for particles.
Temperature control of the Development process is best done by standing the Tanks/Measuring Cylinders and Chemicals in a cool tempering bath and using cooled water for the dilution water. A handy generous supply to ice cubes helps enormously.
For the final rinse (in conjunction with a wetting agent) it will be worth using the purest water you can manage either Particle then Carbon Filtered or Bottled
Under your circumstances it will be better not to wipe the wet film with anything, so some wetting agent (to break the waters surface tension) for the final wash will be essential. Ilfotol is as good as any -
