Has it been in that container for 2 years? It may just be potbound. I'd suggest putting it into a larger container with new soil and cutting it back by about 1/3 to stimulated new growth.

I have trimmed it. But yeah it's been in the same pot lol.

I have mine planted in the ground and they do fine.

Just repot it, add new soil that has some starter fertilizer in it, trim it and it should be fine.

Just a little too much sun. It's trying to adapt. It's just showing you its preference!
