Spanish Tourism Visa Rejection

Hello there, I am a Jordanian passport holder living there and I applied for a tourism visa For a trip with my friends in Mid June. I received a rejection from BLS with the following reasons: travel purpose is not reliable and reasonable doubt of returning before expiry. I’m thinking of reapplying again or appealing the decision. All my documents have been carefully provided, except a cover letter as it wasn’t on the checklist I received from them Initially.

Just a quick walkthrough through my papers: I submitted 2 hotel confirmation from booking.com, one in Valencia and the other in Madrid. Both paid and everything, 2 way flight from ryan air, a travel itinerary, a 3 month bank statement with a 3500$ balance for a week’s travel, Employment letter, travel insurance… The whole shenanigans. Keep in mind that I am 23 and this would be my first Schengen application

Now the issue is, I sent out an email asking for an appeal appointment and was granted one next week, should I go forth with it or just reapply again, cuz I’ve heard that appeals rarely get regarded and approved. I also was asked to write an appeal letter in Spanish????

I want to provide them with a cover letter, proof of possession (Car) and any other thing you may advise me to. (Should those be in spanish too lol?)

The FOMO is really kicking in and I’d be pissed if i get rejected. I do not intend to overstay whatsoever and I need help.
