Do i have ocd? Mental Health

    to have the it and if can my things with in several
    
Do i have ocd?
- checking if everything is turned off several times before i go to bed
- washing my hands ALL the time, i have to do it even if i have thouched just a door knob(hands starting to bleed
- have to walk on certain tiles
- having trouble deciding on the most simpliest of things
- everything i see needs to be in line (like my garbage can for instance, it has to stay in the corner, back and side in line with the walls
- can´t sleep with window closed (which leads to checking it several times)
- can´t sleep if i haven´t said my prayers (and repeating it several times, if i haven´t said it properly)
- have to count things (street lights, tiles, etc.)
- i HATE the number 6, and my favorite is 7
- having %26quot;violent%26quot; thoughts which i am afraid that i might act out

these are just some of the things i do everyday, but lately these %26quot;symptoms%26quot; are starting to get worse, and i keep hitting depressions.
i have been thinking about going to a doctor for a while, but can´t decide if it is OCD
