Did I buy the wrong board?

Hi everybody
I moved to Bali for a year about 18 months ago and started surfing but my head was turned by Bintangs and didn't get out enough. The last 3 months I was probably averaging about 3 times a week and was renting a 7'2 which I had a reasonable success rate at catching waves and could do an ugly bottom turn and sort of drift along the wave.
I am back in Bali after roughly 8 months of zero surfing. Rented a 7'6 a few times then decided to take the plunge with a cheap little banger to practice on when I wanted so I bought a cheap 7'2 from a buy and sell Facebook group. I must confess my knowledge is very limited and I don't really know what I'm looking for in a board. It is 7'2 x 21 x 2 5/8. The nose is pointier than anything I've ever surfed and it feels pretty thin but I don't know if that's because I went out today and got my boardies pulled down and spanked by mother nature. Was struggling to balance on it at sometimes to be honest.
I'm 36, in reasonable shape but need to get my paddle fitness back and weigh circa 75kg or roughly 165lbs.
I'll try and post a pic of it if I can figure out how but does it sound like a reasonable board for me? All the people I live with have these sexy little shortboards and I eye them with envy but they don't catch many waves and I wanted to give myself a chance instead of pander to my ego!
If this is a frustrating question missing variables please forgive me. My technical knowledge is poor and my bottom is sore from the spanking.
Thanks
