For the past year I really have changed a lot. I'm normally a really happy girl. Always silly, laughing and smiling. Never really in a bad mood much. I seriously can't remember the last time I was genuinely happy.

Particularly in the past few months, my mood is just out of control. I'm content one minute, then something will set me off and I'll just be in the WORST mood ever. I'll either be extremely angry, sad, annoyed, etc. Any negative feeling you can think of. In the end, everyone pisses me off and I usually feel like absolute crap and end up crying. To put it basically, I'm always just really cranky and in a grumpy mood. I come off as a huge bitch, and I hate it cause no matter how hard I tell myself to cheer up, I just can't make the negative thoughts go away... this happens every day.

Also, things that usually interest me just don't really entice me anymore. I used to love watching my favourite tv shows online nightly for hours, but I just can't really bring myself to do so. It's not like I don't like them anymore, it's as if I'm too lazy to do so, or I see no point in doing it. It's really strange.

I'm not really motivated to go out and see my friends either. Like I will do it, but I don't get that excited to see them. I feel like I can do something else instead.

Also, I've been recently obsessed with working out. I don't know why. I've always had low self esteem and tried to make myself look good in every moment, but I've been actually trying to go to the gym soooo much. Oh and I constantly think I'm fat, when I'm the skinniest out of all my friends.

Just overall, I feel kinda crazy and psycho. I hate how I can never just be in a good mood, and I let irrelevant matters upset me waaaay too much. I don't know if it's something to do with my hormones, emotional disorder, or maybe depression or bipolar disorder, but if anyone who thinks they have some sort of advice they could help me with, I would really appreciate it. I'm getting desperate :( I don't know what's wrong with me and I don't know what I should do cause of it.

it could be all kinds of things. if it continues you should think about seeing a doctor. take care.

Sounds a lot like just depression to me. I mean it could be manic and this could be your first episode, but suffers don't usually pick up on the problem.
Mood swings and the low selfesteem just seem like your typical depression, when I say typical, I don't mean that its any less important to anything else that could be wrong, so go see you're doctor imediately, even if its just to make them aware of the situation, the doctor will probably acknolwedge whats happening to you and arrange another appointment for something in the near future to see how you're doing.

I think it seems like you are going through some kind of depression.I'm not sure if it really is something like that,cause it might go away,but since it has lasted a year,I believe you should visit a doctor and talk about it.Getting professional help might make it easier to see where you stand and how to face it.Hope things will get better soon..
