PLEASE HELP!!!!

Marisa • Wife & Mommy of 2 boys 💙💙
 I've been having muscle pains (weakness) and joint stiffness and pains as well.. To the point I feel like I can't move or I get an aggravating feeling when I move. I have it in my wrists, ankles, fingers, toes, knees and shoulders.. I feel like I constantly need to pop my knuckles and I get neck tightness and even in my head! I had this while I was pregnant also.. And it got worse after I'm 2 months postpartum and I was diagnosing my self the horrible diseases lol like ALS, MS etc. I made my self so worked up I have panic attacks everyday and constant anxiety, my muscle twitch also and I constantly feel like my body is shaking which is probably due to anxiety!! So now I'm seeing a mental health specialist to treat anxiety and I saw my neurologist and he ran an MRI and it was perfect! And all my blood test are normal! So I'm guessing this is all my anxiety and postpartum!! Today is the first day I feel normal with little to no anxiety but these problems I feel are being my anxiety back but idk.. If this is my anxiety wearing on my body or if it's vise versa
