Do i have depresion?

A month ago i began to obses over being clean from my . I had a problem with not getting sufficient fiber and it made me get kinda dirty down there. Due to my over obsessive attentino to my bowel movement / going to the bathroom i aquired a sort of tic where i tense my colon musle. At the same time i got a new job and my dad left my hous and moved out. I am not sure why but i began to have these crazy mood swings where i wuold cry all of a sudden. Then i began to feel a big desperation due to my new tic compressing the colon muscle. I whenet to the doctor and told her about my bathrrom problem and the doctor gave me some fiber. This fixed my bathroom problem but the tic remained! and i think i got depression. For the last three weeks i have been through hell. All day i would think negetive thoughts like if i was normal or crazy. I would obsses about my depression state. Today i feel the same i am sick and tired of feeling tired and sad. I have not been able to sleep good for days.
