If you are concerned, call your doctor and talk to them. Personally, it sounds like you have a lot going on right now. That combined with your hormones being all sorts of wacky can contribute to the way you are feeling. If it's not PPD, sometimes, just getting out of the house and walking or spending time with friends and having a conversation with adults can help you feel a little better.
Also, please consider changing your SN. PERSEC is a huge thing around here. When you sign up with TB/TN/TK, they highly recommend you not use any part of your real name when choosing a SN. There are way too many creepers who lurk on these boards. There have been ladies in the past who have had issues with stalkers from these boards.
