Does anyone got an idea what to do in such tiredness?

Hi!

Had lots of attacks and very brittle asthma. Feel soo much tired just laying in bed the whole day makes me feel tired. Try to open a pack of dried fruit but couldnt open it. Was struggling even with a knife. Very weak. Tried to go on the bus as well but fell down as the driver didnt wait till i sat down. Also writing is impossible as i m soo shaky (not from salbutamol as didnt use it) what can i do to get some energy? I eat a healthy diet and am a healthy weight.

Thanks in advance
