Hello

Hi, I'd like to be able to swim. Right now I can freestyle 4 lengths of a 25 yard pool before I'm completely exhausted. I'm not fast either. Clearly I'm doing it wrong. 1. First of all, I breathe on only one side. I've tried the rotary breathing but not only does breathing on the other side feel awkward, I run out of air quickly and feel I'm drowning. 2. When I run out of air my body becomes all stiff and my legs sag. No matter how hard I try calming myself I can't get over the drowning sensation. 3. My legs do very little to propel me forward. I've used a board and a pull float and found that it takes almost twice as long for me to swim a lap with just my legs as compared to just my arms. Both are pretty slow. 4. I feel I have buoyancy issues. I cannot dead-float in a pool but I can do it in the ocean. 5. Last but not the least, I have allergy related asthma. I have a fleeting suspicion that chlorine triggers it. Please help me swim. Thanks in advance for your help.
