Zoloft 50mg getting back on

So I went off my Zoloft thinking I could handle it, but I was WRONG. My anxiety and everything has been HORRIBLE. I have been off for about 3 months now I am scared when I start again I am going to feel all weird! Do you think because it was already in my system I won’t go through all the same side effects? I hate the beginning of anxiety meds but I seriously have anxiety everyday about heart attacks having a stroke a aneurysm it’s always something and I am tired of it 😞
