Try to focus on the pleasant things, sometimes when the negative emotions come to you, you may feel out of control, You must immediately tell yourself stop to think of it and go to pray, so that you may once again go back to the pleasant things. All you need to do is tell your brain, in a way it will remember, that it`s yourself and your reaction causes the weird or negative things. Once again to remind you that there is nothing that will makes you anxious or afraid in Christ.
May God bless you ~ peace and joy ~ Have a blessed life :)
