End of this Surfboard?

Hello!
This is my first post, but I am looking for advice on what I should do with my surfboard. I just started learning to surf this June with this 7'11'' Willen board I got used for $100. It was a great deal; the board was not cheap when the seller first got it, but it has just been used over the years. There are a lot of small dents all over, and a lot of cracks/dings/holes that had been professionally repaired (you can see in the pictures.) So the other day I noticed that one of the holes had and the cracks on the bottom had opened up, and then looked closely at the repaired wounds on the nose of the board and saw that most of them were opening. There are cracks around the edges that opened, a little ding by the fin, and holes cracking open most other wounds. And worst of all theres this ding on the thin nose part that looks like its cracking open vertically (you can see in the picture.)
So after looking it up, it doesn't seem like repairing your own dings isn't that hard. Although this board has been awesome to learn on and a lot of fun, Im not sure if it's worth it. If its previous owner had all of these professionally repaired, and just a couple of months of soft surfing opened them up again, is it a sign that it's time has come? What do you guys think about repairing it? Having it professionally repaired would probably cost more than it did, right? Plus, that crack on the nose looks pretty serious, right?
If you do think I should let it rest, what do you think would be a good board to transition to? I've just started to catch small crashing waves, instead of whitewash waves, and I feel like I am improving every time. After this, should I go for a shorter lighter board now and just try my best with it? What would you recommend?
Thank you so much!
