Hi There, I Am 24 Turning 25 End Of This

hi there, i am 24 turning 25 end of this month. I am 6 weeks into life with a newborn (my first) and i am also trying to complete a teaching degree. I really feel life is getting on top of me.. i wouldnt regard myself as depressed... just very stressed and uptight. i dont want to go to my doctor or speak to anyone about it because i feel they will assume its post natal depression and i dont want anything like that on my records because if i ever do split with my partner (which is a likely option at the moment) i dont want to give him a reason to take my baby away from me. im thinking of buying the kalms tablets just to make me relax and be a bit more laid back to things... do you think this will help me. if not what other over the counter medicine can you recommend ? im literally flipping out if he doesnt wash her bottles properly...
