Need help;

Recently I’m getting stressed about myself time and again. It’s like reason unknown and thinking alot, and unable to concentrate on anything.

Things I’m going thru:

1. I’m keeping myself away from people and not talking to anyone except for work related, even with family and friends. Stopped talking to all my friends and family.
2. Changed job recently and unable to concentrate on work related; like I used to find pleasure while working on a lot of things and used to perform great under stress, while here, I’m finding myself asking help for the very little things. And current job being wfh till now is aiding as well.
3. Not willing to move outside or get some physical work done. Tried going out; went back to home place and none are helping. Am going for a walk in the evenings and as soon as I’m back home, feels like going back to the shell.

Not able to put things in words but gradually I’m losing all my motivation. At nights it becomes way difficult to sleep and a lot of dreams and I wake up exhausted.
