chains of chemistry

i am feeling so sulky today. i am not sure if not getting enough sleep really kept me at even an even keel but it makes me feel unsatisfied with myself. Also making decision and conducting my behavior seem really difficult for me. it feels as if i can access situations well and pick up the right behavior. this is not too good as it is making me irritable. very often i question myself if am i stepping over the line, i do not wish to replace/overtake anyone, take away any of your belongings. i just wanna be well acknowledge and loved by my friends and thats all. am i asking too much?
