Need help meditation and visualisation blockage

I’m having a seriously tough time meditating and especially visualisation!! I think my Chakras are possibly blocked , i grind my teth, joint pain , low self esteem, don’t seem to be able to follow anything through , feel inferior. any help with how I go about unblocking please

I am drawn to the sea , to the point I now live next to the beach, (pebbley not sand). I feel very relaxed and at peace here , just sitting next to the sea, the sound of the waves crashing against the shore ,my happy place , so I’m trying my meditation here , but still feel Theres a massave blockage, not letting me see past !! when I close my eyes all I see is what I’m interpreting as big dragon eye blinking and then staring back at me !! wtf does this mean !
