perhaps if you call your priest he can set something up, like perhaps he knows someone who can pick you up or something…
well, although i know we should never, by our own will, put off confession, but maybe God is letting this happen to give you more time to prepare yourself…of course i have no idea, i’m sure you are trying to prepare as much as you can, but it’s a thought anyways,
but be at peace…even before confession God can forgive you, as long as you truly intend to go and are dead set on doing so, and you must still go even still,
because remember the lepers which wished to be healed by Jesus? and he told them to go to the priest, and just on their way they were healed, well, of course they carried out his command, and one seeing he was healed, came back to Jesus, and fell on his knees giving thanks, and Jesus said to him - “Were not ten made clean? and where are the nine? There is no one found to return and give glory to God, but this stranger. And he said to him: Arise, go thy way; for thy faith hath made thee whole.”
just do what you can, try your best, but do not stress, God knows your intention to go, He knows your regret and sorrow for your sins, and although i’m sure you will make it to confession soon enough, even if you were to die before then(God forbid) you would be forgiven.
ok…hope this helps, take care.
