Will my nails ever grow out normally?!

I REGRET IT!!! JUst turned 18 yesterday and it now hits me hard. Wat have l been doing all these years. Been biting my nails since l was a baby. It has become addictive to the point that even if l want to stop i will suddenly find myself biting them again. I have grown em out 2 times like for a few months (2-3) they grow out brittle and my fingernails just remain so small. Will they ever increase in size and shape or im stuck forever? i really wanna stop now.

I think the smallest one is really cute to some extent idk😭😭 Do u think fake Nails will save me? Will my nails & fingernails ever grow out normally? My toes suck the most ugh!
