You shouldn't feel so bad. Leetcode problems are tough, even the easier ones, and I have 10 years experience. When I was looking for a new job last year, I could barely finish one or two of them and felt pretty discouraged. But with practice, they become a lot easier and I was knocking them out. The problems are hard because they cover an area of programming that most developers don't work with everyday. It's a separate skill set. I highly recommend Georgia Tech's online master's program. It's ranked in the top 10 of all CS programs worldwide. The total cost of the program is under $10,000, and you can take a class part time while you're working full time. I'm halfway through the program myself, and it's definitely helped me keep my skills relevant especially since certain technologies didn't exist when I got my Bachelor's in 2008.
