Hi, I Am 43 Year Old Woman, And I Have

Hi, I am 43 year old woman, and I have been in and out of depression for years, I usually take Zoloft 50mg and it helps alot after a month of use with uncontrollable crying, it make me feel numb. however, I had a loss in my family 5 months ago, and many issues in my family life, that now after being on Zoloft for 2 months again, I think its working some for the crying , but now I have found to feel like a doomed feeling and having what I think are panic attacks, I feel out of air, I feel nervous, shaky, stomache pains, and a feeling of wanting this feeling to end
