Procrastination/perfectionism - would really like some help!

Hi, I wonder if anyone can advise me on which homeopathic remedy might help me with this? Sorry it's so long - if anyone can read even a bit of it I'd appreciate it - I just thought I'd try to answer all the questions that the different posters here have specified.

My major problem at the moment is procrastination (about academic and literary work, but I have the same attitude to most other things in my life too). I have anxiety about it most of the time, and sometimes headaches. I get much too perfectionist and caught up in details, rereading every sentence I write many times, rewriting it trying to be more and more precise so that people will understand my exact meaning, etc. I feel like I have to spend ages thinking every idea through, considering every last thing that might affect it. Any simple choice or decision about what viewpoint to take, or simple explanation of a point, gets more and more complicated in my mind until I feel like I can't possibly give an answer or make a decision because it can't possibly be completely and finally 'correct' - even if i addressed all possible problems another factor will arise in the future that changes or invalidates things, so I have to turn away from it with the feeling that it is impossibly huge and complex. I suppose I would say that I'm obsessed with finding perfect solutions that cover all the bases and solve all possible problems once and for all. As you might expect, this often makes me become exhausted!

Criticism upsets me a lot and I worry that people think that I am incompetent and 'abnormal' and that they don't like me. I tend to withdraw and shut myself away. I want to lie down and sit with my legs crossed or tucked up. I tend to stay up at night and sleep during the day. I bite the inside of my mouth and clench and grind my teeth, especially when anxious. I push back strands of my hair somewhat obsessively when I feel self-conscious. I tend to hold my breath and sigh, and I tend to twist my face into a worried, frowning expression. I take everything very seriously.

Lately i have also had a sore throat that feels dry and irritated, with mucous that seems to stick in the throat for a long time. Also my left eye has been very dry and red in the inner corner a couple of times. Dry air seems to make this worse, and I have wanted a more humid atmosphere and i have wanted to drink cold water often, although usually i dislike cold water and mostly drink hot, fruit-flavoured herbal teas. I have tense muscles and hunch my shoulders a lot. I am hungry a lot but often put off eating. I like fruit, vegetables, cheese, sour cream, eggs and custard. I don't like bread much, and I don't like smoked things.

After sitting and worrying about it all for several hours I sometimes feel a spontaneous optimism and pleasure. I often feel dread and despair when I wake up. Sometimes I am very sensitive to noise and light and seeing moving objects, and feel overwhelmed by all the sensory information. I often have a similar feeling from thinking - my mind and heart race and I have lots of ideas in quick succession, but I don't feel calm or rational enough to elaborate them clearly and in a balanced way in writing.

I usually have very cold, sweaty hands and feet, which become warm in bed. My neck, chest and upper abdomen feel warm and my armpits and between my legs are quite sweaty. I have a weak back and lower stomach muscles, and often get muscle cramps in my upper back and in the arch of my right foot. My bowels are very changeable from one extreme to the other and i have strong cramping before and during bowel movements. I am thin but not muscular, with very pale skin. I have dark hair and quite a lot of body hair which is also dark. I get red spots on my face. I have crowded teeth and no cavities. I often have a weak, heavy feeling in my bladder. I have a weak voice and my breathing doesn't feel comfortable. When I am at my worst I fear that I will isolate myself and drive myself mad, and being physically and mentally incapable, and the future.

I like being consoled. My periods are long and quite light and quite dark, and the last one I had was even more so. I sleep on either side with my legs partly tucked up.
I don't like cold, wind, rain, bright sun or extreme heat - I prefer mild weather.

If anyone's made it to the end of this and can help, then thanks a million!
