UPDATE:
the gaelic gods i contacted replied to me and i got some advice but i have to go outside for it 
anyway after building up confidence for the whole day i went with option 4 and just sent a long awkward message to someone i dont know at all, i am now awaiting a response, wish me luck because i am terrified
day 2 update
so far nothing has really happened but i have four methods i can use to get information and/or find somebody
message a gaelic learning organization and ask for advice (already done)
someone in my school knows somebody who goes to a gaelic school, i could get in contact with that person from my school and ask to get in contact with the person from the gaelic school
i go to a gaelic conversation group, however everyone there is a lot older than me, i could ask them about it or if they know anyone my age (the gaelic group is closed for the summer though so i cant do this one at the moment)
(my gf suggested this one) look through the followers of gaelic related accounts, follow someone from there, try and become friends (i could NOT do this one)
i officially declare this as a new zlf side quest!! wish me luck finding this person!!
last night i was sitting on the edge of my bed and imagining what life would be like if i had friends who spoke gaelic
i need to go on a side quest to find someone my age who speaks gaelic
