How to deal with too many deadlines at work when you don't get along with your co-workers and its hard to ask them for help?

I think it is beneficial to make a timeline of various deadlines and stick to the schedule. Depending on how you do not get along with your coworkers, you can kindly ask for help in a small manner and think of this possibly being an opportunity to foster a better relationship with your coworkers if there is a good outcome.

Stress at work is horrible. It’s made worse by the fact that you dislike your colleagues and feel that you cant talk to them. There’s no simple solution to this unfortunately. You need to either raise the issue with management; you have too much work and your colleagues can’t be relied upon, you transfer internally to another team or department, you look for work in another firm or you buckle down and deal with one job at a time. Prioritise your work. Deal with the hardest tasks first thing in the morning, leaving the rest of the day for smaller, easier work. One problem and one job at a time. The other option, and probably the best and most effective immediately, would be to try and be friends with your colleagues. We’re adults now, we should be able to act like it and resolve our differences. Agree to disagree. Attempt to resolve the situation and force yourself into getting along with them, or at least talking to them. While you may not like them, if you swallow your pride and ask for help it will make for a much easier work life. Like I said, no easy options or quick fixes, but at least there are options and ways of dealing with it. Don't leave it to fester, make up your mind and take action today or it'll just feel worse. Once you've dealt with it and asked for help, the next times wont feel so bad and you'll be happier and less stressed than you are now. If this fails, see the options above!

Do your best to time manage. Place the projects in list of importance and put your all into it! If it is absolutely not possible, request for an extension or try and find a co-worker who can help.

Your only 1 person. If it seems unreasonable I would be talking to my boss and asking them to prioritize what is most important to least important so you can get the work done on time.

Always give a realistic date of when you can complete each task then organize the task according to the deadlines that you have given yourself. Always leave room for learning and improvement when time is concern.
