I feel so helpless and lonely and overwhelmed ... I am going insane in silence ...please anyone tell me i am not alone or something ....let me start saying I love my son and my fiance but i feel like i can not take care of myself ... My fiance is in rehab and i had surgery on my foot so i can not walk and my son is crawling and it hard to keep up with him ... My Dr said take it easy but i can't when these things are going on .. my mil does not understand I don't think so my foot is swollen and i can not take care of it cause i have a baby who needs my attetion 24 7 .. It would help if she would take him for the night ... Plus she said i was being lazy ..omfg no it is called i did everything when ur son layed on his ass i did everything and i have to take it easy ...i forgave ur son ... My Dr is going to be pisst cause i had to run the other day cause my dad was abusing me with my child ...and i am trying my best but i need a break and plus now i am sick and i feel awful ..there is more but I already feel like i typed a lot
