20mg of lexapro and taking klonopin

has anyone experienced some side effects like fog, dizzy shaky when going from 10 mg to 20 mg of lexapro? ive been on 20 mg for a week - 4 weeks on 10 and still dealing w tough health anxiety, panic and dont want to leave house. the mornings are the worst for me and trying therapy as well im nearly 50 now and had a similar experience right before 40 and talk celexa and xanax back then but was completely off meds . now feel like a failure again. sucks but thankful for this forum
