On lexapro, when to expect relief

[Guest guest]

My 20 year old is experiencing severe anxiety and constant thoughts around him

being a bad person. It first started after cheating one time on his gfiend he

has had 4 months. He told her and they are stayign together. But he can't let

this go and now tells me his whole life he has been so selfish and needs to do

good things. He started on Celexa for 7 days. Then pdoc switched him to Lexapro

b/c anxiety and thoughts (told me he thought he was going crazy) were so bad.

Now on 10 mg. Lex. for 10 days. Total about 2 weeks on SSRI. Also, stopped

smoking marij. since this started. Marij. was causing extreme anxiety.

He started working at a camp that he has worked before at.Started 4 days ago. No

counseling there but has friends there. Texted me yesterday about still no

relief from the anxiety/thoughts. Have been telling him to give it time and try

to " power " through. Trying to be positive but worried myself. How long to give

this med. time. Lex. works for my anxiety. Husband and daughter taking Zoloft

for their anxiety stuff. Daughter maxed out on Celexa. Having better luck with

the zoloft. Any ideas? Thanks.
