it literally makes me want to kill myself daily

Yes, those doing IT and R&D workers are likely to have such feeling. It's matter of little or very much hard feeling.

You must do it gradually and adapt it, interacting with people. Practice a good effective communication with people before head in marketing, event planner, investment company. Never get culture shock in new company. If you do, act steady, firm, stay focus.

Join an event such as charity, running program, party etc. make yourself comfortable when in the crowd.

There are plenty of group in FB. Search the key word and click on group/ page. Choose which is nearest to your house.

TS, if you want to change of pace, why not start with some society activities first? Let yourself slowly adapt to the changes, be more pro-active, meeting new people, busy events, and step out from your comfort zone.

I also work alone, just that my job requires alot of communication, understanding of needs. Sometimes I feel like i working in a dessert island with nobody. It's good you want to make the change, when you have the will, you'll have the way.

I will agree with this. I will consider myself as socially awkward too
This.

TS, you need to have a gradually changes in your environment, you cannot straight away start applying such jobs that needed a lot of human interactions. After awhile, you will feel drained.

So you slowly join social activities, slowly adapt and gauge your enegy level. If you feel like you are at the stage where you can social fine then go ahead
Many people feel lonely too. It's a pandemic.

Some told me they join religion activities for this. And one guy told me, we needed to have contact and interact with people to curb the loneliness in our mind. So, he went and join jujutsu classes. Every week, he will have sufficient interaction and contact with other humans, and he feel good after that. You can consider this

seem u have no self confidence at all.. try join hiking group, go gym, u can gain confidence there. i saw a lot of ppl very shy2 at gym, after 1,2 month all become bro already. i swear lol

If you are not planning a family, marketing event jobs are best suited for singles or married people who don;t want kids.

Thats because bosses want commitment to come during the weekends and at times work late nights to ensure the event is success.

if you have anxiety this role is not suitable for you. You need to be a good communicator and coordinator, to talk to your agencies and contractors to get the work done.

This job is for extroverts.

You also must be very forthcoming, good organizer and gain the trust of your boss. If you are a kura-kura everything keep to yourself, your boss ask you how is the event planning? can you do presentation or allay his worries or not?

If you want to do this role, better start from ground up to get use to it. Make sure you work in a team, some companies rely on 1 or 2 event people, then you will be struggling. Work in bigger companies, bigger teams, so someone can cover for your novice as you are just beginning.

You also must make sure you don't do mistakes, if forgot to invite VIP, or disorganize/sequence of the event out make confusion, or mishandling of press or forgot some props, timing of events off plan....you kena kaw kaw....

No harm to try marketing. But try from scratch. Don't join those one or two man teams, else you be expected to do everything, then your social anxiety would be overwhelmed. Join bigger teams.

You sure you want marketing event?

I really don't know what else job you can try. Most jobs require communication even IT.
