Life's a bitch

I'm just venting a little. I'm currently attending cosmetology school and I only have 4 months left.  But my heart isn't in it. I don't have a love for doing hair. I only did it so I would have something to do and so I would t feel like I'm disappointing my mom. I'm 21 and I don't have my life together. I'm constantly depressed because I feel like I'm not going anywhere in life and I have no effen clue what I want to do. It just sucks and hurt so much that I'm utterly and completely lost....I just don't know what to do......ever since my brother died 2 years ago everything just went to straight to hell....I just can't seem to get it together....I've just been struggling with no clear path in sight....
