Talk to Psychologist on Depression

every now and then I feel like this heaviness overtaking me, and I get emotional on the tiniest of things which normally wouldn't bother me in the normal days. Sometimes the tears keep falling off and I don't even know what is the reason behind them. I am an introvert person and I have a very small group of friends and I am not close to my parents because of a multiple of reasons. I have tried to connect with them but it just feels impossible and puts me out of my comfort zone. I used to have a diary in which I used to write my feelings out but lately, i've lost the will to write in it as well. 5-6 years back I started self-harming but I pulled my self out of it on my own and I have not harmed my self since then but every time I am in such state of being so lost, the same thoughts start to come back and they push me to convert this emotional pain into physical pain. I don't really feel like talking about what I feel because I don't think anyone can understand what I am going through
