so tired of feeling bad

i just so tired of being tired and feeling bad.  i want to feel joy and freedom at least part of the time.  that seems like it should be a birthright.  today i am very sluggish.  i should get off the computer.  didn't find anything on netflix.  at least i went out shopping and took a 2 minute walk.  i think i am going to lie down for 20 minutes or something.  sometimes i feel like i can't get enough air.  it's probably anxiety but i don't know.  it feels awful.
