Weird emotions, help? Does anyone else ever feel this? What is it called? How do I stop it?

Does anyone ever get really weird emotions? indescribable ones?

Its like you are half-way not there but you are there but you can never describe the feeling kind of like a big block in your head, you want to scratch your skin off and become something new... and I always get this feeling randomly and I say or do stupid irrational things when I get in that mood

Sorry I'm not describing it well, I never can explain it to anyone, not to my therapist, not even to myself. They are usually very short lived, but very, very intense.

Does anyone at least have any direction of what this is? I was diagnosed with depression, anxiety, and a possibility of aspergers...im not sure if that helps.....my moms side of the family have thyroid/bpd problems.
