I have been suffering from some kind of anxiety( i guess) since the past 5 years. It all started with a panic attack and that incident has filled my mind with fear and negativity so much that they nowadays come to me quite regularly and disturb me so much. I used to be someone emotionally strong and optimistic about everything but that one incident has changed me so much and till now i have not been able to come out of it. I have been very optimistic all these years that i will be completely okay again and sometimes I feel like I am very near to getting rid of all these but sometimes I am back engrossed so much into negativity. I feel like I may lose my mind and the biggest trouble is that i am unable to convince my mind that everything is alright and it is just thoughts. Rather my mind takes over me. I want to get my life back, my concentration and emotional strength back. Sometimes i also feel like I am getting trapped in unnecessary thoughts so much that I am unable to come out to reality. Please suggest me something.
