hi maria
the thing u are having in the mind is neither true nor important . think any issues with little perspective without any judgement. think in term of different perspective.please keep yourself busy by going outside and talking with your friends ,watching tv, listening music, reading newspaper, hobbies. dont avoid any situation because of your anxiety .try to face everything. dont think extremely and be flexible.remind yourself since you are feeling bad nothing bad is going to happen and you are not bad. i pray to god to give you stength and courage
